1449422 - Sometimes vertical borders of buttons are not removed when focus is lost

Status: RESOLVED DUPLICATE of bug 1349646

(Core :: Graphics, defect, P3)

Description

[Mantaroh Yoshinaga[:mantaroh]]

Attachment: button-with-solid-test-case

Gecko doesn't remove the solid border of a button element in the devtools menu button.

STR:
 1. Open the devtool.
 2. Select any toolbar button. (e.g. Inspector)
    (Note that some tool panel steals the focus. If lost the focus of button, refocus to the button.)
 3. Press the right arrow key.
 4. Repeat the step 3.

AR: A solid border has remained.
ER: The unfocused solid border of a button is removed.

An attachment file is another test case, the result is same. (i.e. border has remained.)

I think this problem isn't limited to border-style: solid but can be reproduced with other border styles.

Using attachment 8963009 [details] I notice that at least on Windows I need to press Tab once to focus the element before I can reproduce. (That is, the dotted line from the focus styles interfere somehow.)

I think this is a dup of bug 1349646.

This doesn't happen on Firefox 52, I am pretty sure this is a dup of bug 1349646.
