1782396 - Clicking, switching tabs, and clicking again registers as bloth a single-click and a double-click.

Status: NEW

(Firefox :: Tabbed Browser, defect)

Description

[mbartelsmanm]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:103.0) Gecko/20100101 Firefox/103.0

Steps to reproduce:

This is evident when using YouTube.

Open a YouTube video, and open another tab. In the other tab click somewhere around where the video would be in the YouTube tab, switch tabs using the keyboard, and click on the video once. This has to be done quickly, in the timespan that a normal double click would take.

Actual results:

A single click is registered in both tabs, but an additional double-click is registered in the second one, even though only one click occurred per tab.

In the case of YouTube, this is evidenced by the video pausing/resuming, and then going to fullscreen mode, as if it had been clicked, and then double-clicked.

Expected results:

Only one click should register in both tabs.

Simplifying the STR from comment 0:

1. Open two youtube video tabs (anyvideo)
2. In a fast manner click + Ctrl+Tab + click

Expected would be that each video is played/paused - 1 click recorded.
Actual is that after the tab switch, on 2nd tab we somehow record a double click.
