1683048 - Selected content document should not capture keyup event when selecting the browser by Alt+Tab

Status: NEW

(Firefox :: Tabbed Browser, defect, P3)

Description

[Daisuke Akatsuka (:daisuke)]

As reported in bug 1681217#c6, when selecting the browser by Alt+Tab, the content document captures the keyup event.
In this bug, we will avoid sending the keyup event at that time.

STRs:

1. open the attached html of bug 1681217.
2. type Alt+Tab key and select the browser that is opening the attached html.

ER: The browser just will be selected.
AR: The test document of selected browser captures the keyup event, then shows an alert.

I add explanation about STR.
If the browser is already focused and select the same browser again by Alt+Tab, keydown of the beginning of selection and keyup is passed to the content document. But, if another application is focused at first, and selecting the browser, the key events won’t be sent to the content.

If we resolve this issue, we might need to know if it had become application selection mode since it seems we can capture the Alt event but can't capture Tab event of selecting of application.
