Details

setJumpToMessage also uses document.getElementById, element.scrollIntoView and a small setTimeout to delay closing the thread, to scroll to a message (in MessageAggregator.js). I have used the same procedure.

Hi @Abbas-Askari

Thanks for the fix, can you please also maintain scroll position whenever a message is starred / pinned/reacting to emojis etc.. some do, some don't.. Can we make it consistent

[Abbas-Askari]

Sure! I update!
