Status: VERIFIED FIXED

(Firefox :: Tabbed Browser, enhancement, P1)

Description

In order to further improve sensitivity issues with the interaction cue, adjust when the timer for the delay starts and is reset, similar to tab group dragover behaviour.

[Tracking Requested - why for this release]: Potential dot release candidate but would like QA testing in Nightly/beta to ensure there aren't any unintended side effects.

This issue is verified as fixed in our latest Beta 144.0b5 as well as our latest Nightly build 145.0a1 (2025-09-23), There is a slight delay before the animation to pin tabs hits and it makes it harder for users to accidentally pin tabs.
