See attached screenshot. The "handles" of the selection are not part of the contentRect. Therefore the floating toolbar might cover them. To avoid this we can either include the handles into the contentRect or always add some static bottom padding to the rect manually.
The b2g floating text selection dialog addressed this issue by adding a constant pixels [1] so that it won't cover the carects . A good reference is the spec version 1.7 page 17 in bug 921965. The function calculateDialogPostion() to calculate the text selection dialog position is at [1]. cc Jeremy that he knows the details about the positioning.

Capella, TYLin: Has someone of you time to look into this (Additionally I'll mark it as mentor bug)? It's always at the bottom of my queue and I never get to it. This is where we get the rect from gecko and calculate the rect for Android: https://dxr.mozilla.org/mozilla-central/source/mobile/android/base/java/org/mozilla/gecko/text/FloatingToolbarTextSelection.java#173-190

I haven't looked, but this sounds reasonable on the face of it. I'd imagine the patch would be a prefable option on the AccessibleCaretManager side.

Doing this on Java side might be a bit hacky. :)
It'll be easier to get the caret rects from AccessibleCaretManager. However, I'd rather keep the current contentRect, i.e. CaretStateChangedEvent::mBoundingClientRect [1], containing only the selection highlight rect, and add another attribute like mBoundingCaretsRect for the carets rect. Since B2G resolved this issue by adding a constant pixel offsets to its floating toolbar, adding carets rect to the existing rect will break B2G.

I'm trying to fix this bug, but when I try to recreate it, this is what I see. Is there a specific way to cause it?

Is there a specific way to cause it? It looks like you are using an older version of Android. The floating toolbar is only available on Android 6+.

I've been trying to fix this bug for a while now but haven't made much progress. Could I get some pointers on how to solve this, or where to look? I took a look at CaretStateChangedEvent.webidl and it's autogenerated .h file, but haven't found the part where the distance of the floating toolbar from the carets is set.

That's something capella or TYLin might know.

Sebastian, what do you think about the comment 5? I guess it would be simpler if we just add some static bottom space manually when the floating toolbar is below the selection rect. The selection highlight bounding rect |mBoundingClientRect| is set from the C++ side in [1]. I had no idea how floating toolbar uses the |boundingClientRect| in CaretStateChangedEvent.webidl. Sebastian, would you point where the code is? [1] https://dxr.mozilla.org/mozilla-central/rev/5f95858f8ddf21ea2271a12810332efd09eff138/layout/base/AccessibleCaretManager.cpp#1383

Yeah! (I just talked to TYLin in person) I agree. It's much easier to add the offset (size of the handles) to the bottom of the content rect. I guess we want to do it somewhere over here: https://dxr.mozilla.org/mozilla-central/source/mobile/android/base/java/org/mozilla/gecko/text/FloatingToolbarTextSelection.java#176 Or here: https://dxr.mozilla.org/mozilla-central/source/mobile/android/base/java/org/mozilla/gecko/text/FloatingActionModeCallback.java#63 @amol: Do you want to look into this? I guess we basically only need the size of the handles in dp, calculate the actual size in pixels, depending on the device, and add it to the bottom of the rect.

Setting tracking flag: We probably should fix this in 48. We have roughly 5 weeks until merge day. @amol: Do you have time to write a patch for this or should someone else look into this?

@sebastian: can't find the time. Better if someone else takes it up.

I agree we should fix this for 48, but we need an assignee. :TYLin do you have time? :sebastian? Margaret, any other suggestions?

Sorry that I don't have time to take this. I'm out of office next week. I've talked to :sebastian about this bug in London. The approach would be in Java side as described in comment 11.

Okay, I'll write a patch.
