1643153 - After click on compose body, need to press Shift+Tab twice to move focus to subject

Status: NEW

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Thomas D. (:thomas8)]

Moving focus from compose message body to subject is one tab stop, so it should require. Shift+Tab once. This mostly works for keyboard-only operation. However, exactly and only after a left-click in the body, it requires pressing Shift+Tab twice, the first Shift+Tab does nothing. Expected: Single Shift+Tab once should suffice.

I seem to remember seeing this. Not sure when it started - if it wasn't 75 someone can change it.

I can reproduce the issue even if on TB 17esr Windows10.
And also I can reproduce the issue on https://www-archive.mozilla.org/editor/midasdemo/ using Firefox77.0.1.

So, I think this is not TB specific issue, and not a recent regression.

Specifically, after clicking the editable area in midasdemo, two shift-tabs are required to move the focus to the "Size" popup.
