>>> My Info: Win7_64, Nightly 47, 32bit, ID 20160210071115 STR: 1. Open the following "data:" url or click URL in the form above > data:text/html,<div class="declaration"><span></span><span class="value" contenteditable="">linear-gradient(to left, red, blue, green, yellow), url(test.png)</span> <span></span></div> 2. Click on the text on that page (preferably - between "s" and "t" in word "test") 3.A) Hold Right arrow for several seconds 3.B) Press Right arrow 6 times (if you followed advice in Step 2) AR: Caret disappears. Looks like it just leaves [contenteditable] element ER: Caret should be displayed at the end of text in [contenteditable] element This is regression from bug 669026. I'm not sure, so leaving "regressionwindow-wanted" keyword. Regression range: > http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=c5b90ea7e475&tochange=f63a99195987
Your suspected bug looks highly likely to be the culprit, yes.

jet, we'd like to get this fixed but we're getting it off the 47 tracking lists.

Fairly minor regression since 2011. It would be nice to fix but we are not going to track it.

notes (and workaround):

  • the contenteditable is not affected when it has a border
  • also when when it is the last child, hence the . in this proof of concept:
data:text/html,<div><span contenteditable="" style="border: 1px solid black">edit me!</span>.</div>
Severity: normal → S3

Adjust nsFocusManager::GetSelectionLocation so that
it handles the case of moving to the end of a contenteditable
(previously only handled form controls)

This patch shouldn't change behavior. It just removes a lot of noise
from that function.

In particular, it simplifies various conditions that can't happen, like
startNode being a text-node but a form control at the same time, or a
text-node and the root element.
