spell cast odd behaviour inside of instances

WoW Version

TellMeWhen Version

11.2.1

Describe the bug

the icon type (or condition) "spell cast" is passing even after the spell is finished casting.
Noticed it and tested it with lightning lasso (channelled spell, in case that matters). the condition passes when the spell starts casting, but after the spell completes, or is interrupted, the condition will continue to pass for roughly 5 seconds it seems (it's a 5 second spell cast, im not sure if thats just a coincidence)
Have used this condition for years and only started seeing this behaviour in wow patch 11.2. I was using an older version of TMW intially, but upgraded it to 11.2.1 and had the same issue, so something blizzard did with 11.2, I would guess
I Haven't been able to reliably re-create it. sometimes it behaves normally, but often it will not, still trying to find patterns. best chance at recreating ive found is if i spam the cast button even after the spell has started

EDIT Ok i figured out it is very easy to reproduce in instances, and very hard to reproduce in open world

EDIT It seems like after the cast ends, the icon will hide for a millisecond but then immediately comes back as if the cast has started again

This is Blizzard's bug - nothing I can do. Their API is reporting that there really is a second cast immediately when the first one ends - see the jump by essentially exactly 5000 milliseconds. It does indeed continue like that for another 5 seconds.

thanks for looking into this and confirming!
