BitBucket pull request UI duplicating tasks when loading extra lines (BB-13418)

Funny BitBucket bug.

Go to a pull request that has file changes shown for a file so that it does not show all the lines at the start of the file and instead shows that ... ellipses button for loading additional lines

Then add a comment for that file (not for a specific line but for the file itself).

Then add a task on that comment.

Now press the ... ellipses button for loading additional lines at the start of that file... and the added task will get duplicated many times.

Some extra (and most likely unimportant) information: At the time I did this I also already had another comment in the process of being added for that same file, two other comments and a task added for a previous file, and several line comments & tasks throughout the whole pull request.

Using FireFox 38.0.5 on Windows 8.

Extra edit:

The fact that there was another comment on the same file, and that that comment was in edit mode might be relevant after all.

I just have a similar situation when one of the file level comments was in edit mode and then I pressed the ... ellipses button that comment's text edit control got displayed 4 times instead of just once. Pressing Cancel on the last displayed text edit control got rid of all of them.

Also, some extra notes on the extra tasks displayed scenario in the in the original problem report description:

• checking/unchecking the extra task check-boxes seems to turn them on/off in groups of three
• reloading the page got rid of most of the extra tasks, but it seems one per the ... ellipses button click remained and needed to be deleted explicitly afterwards
