459599 - Selection highlight problem with overlapped selection ranges and inlines

Status: RESOLVED WORKSFORME

(Core :: DOM: Selection, defect)

Description

[Uri Bernstein]

Attachment: testcase

When creating a second selection range (using cmd[ctrl]-click-and-drag), if the second range starts before the first range, then extends to overlap it and continues to intersect an inline element, the portion of the selection from the beginning of the inline onwards is not highlighted (but is actually selected!).

This is probably better illustrated by the attached, self-explaining testcase. After following the instructions, only the text before the words "ctrl-select" appears highlighted, even though more text is selected.

I could not reproduce this by scripting the selections - it seems to only happen when actually doing them with the mouse.

Attachment: correct testcase

Sorry, the previous testcase was my failed attempt to do an automatic (scripted) testcase.

Since this also happens on Windows and Linux -> All.

But I don't really understand your description.  Here's what I see:

1) Select anything to the left of the bolded "ctrl-select" text (need
   not be a whole word).

2) Start ctrl- (or cmd-) selecting to the left of what you previously
   selected, and keep dragging the selection to the right.

   The selection stops expanding at the beginning of "ctrl-select".

This problem doesn't happen in FF2 (or for that matter in Safari or
Opera), since they don't support ctrl/cmd-select.

Yes, this is exactly what I was trying to describe. Sorry if my description wasn't clear.

This issue no longer seems to exist in current Firefox; resolving as WFM.
