1827755 - Every change to the unread count of a folder triggers the folder tree mutation observer

Status: RESOLVED FIXED

(Thunderbird :: Folder and Message Lists, defect)

Description

[Geoff Lankow (:darktrojan)]

When the unread count of a folder changes, we change the textContent of a label in the folder tree. Doing that causes a text node to be removed and a new one added, and that triggers the MutationObserver watching for changes in the list.
