1. Load attachment 590476 [details].
2. Drag text over the text input control.
Regular caret at drop location.
Drag feedback caret is faint.
There are some comments about styling in bug 673873 that may be related.
I'm not sure I understand what the bug is actually. Could you be more detailed?
For text inputs without the placeholder showing, the drag feedback caret is black, as expected.
When the placeholder is showing, the drag feedback is the same color as the placeholder - grey.
Indeed. I misunderstood your first comment actually. I hope this could be fixed if we use a pseudo-element instead of a pseudo-class to style the placeholder.
Should we really be showing the placeholder while there's a drag feedback caret? It seems to me that should hide the placeholder anyway.
Hiding the placeholder when showing drag feedback sounds reasonable to me as it gives an indication of what would happen if the drop is made at that mouse position.
Given that bug 673873 wants to make the placeholder stays when the element has the focus but no value, I think the behavior described in comment 5 would be inconsistent.
Also, it might be interesting to see what native UI do here.
Fixed in bug 673873.
Proper fix will be done in bug 737786.
