670809 - Backspace & Delete don't work on first or last character in a selection in contenteditable inline elements (such as spans) nested in another inline element

Status: VERIFIED FIXED

Description

[Aaron Kaluszka]

Step 1: Select text in a contenteditable inline (which is nested in another inline) such that either the first or last character is included in the selection.
Step 2: Press backspace or delete.

Expected Results: All selected text is deleted.

Actual Results:
- If the selection included the first character, only the last character in the selection is deleted and the text is deselected.
- If the selection included the last character, nothing is deleted and the text is deselected.
- If the selection included all characters, nothing is deleted and the text remains selected.

Bug confirmed on Aurora (Fx 7.0a2) but works for me on Nightly (Fx 0.8a1). I couldn’t find the patch that solved this issue.

Fixed by:
167f6642efd4	Fabien Cazenave — Bug 688599 - do not expand selection for deletion outside of the active editing host; r=ehsan When a selection in an inline element is to be deleted, it is first expanded to the parent block in order not to leave any empty inline element. This patch ensures that the selection cannot be expanded outside of the contentEditable element (active editing host).
