Sync conflict while notifications are showing

[wilderjds]

• I have searched for existing issues that may be the same as or related to mine.

When there is a notification open, there is the option to "mark as done" in the notification; however, if the file has been modified externally after the notification appeared, hitting "mark as done" will result in a sync issue (both remote and local files have been modified).
Notice that I force sync-ing of files by calling the intent SYNC_START when the remote file has been touched; the request appears to go through, but (I guess) it is somehow not triggered until too late.
