Add confirmation dialog when marking duplicate a bug that itself has duplicates

[Deryck Hodge]

Now that a branch fixing bug 78596, Automatically handle moving duplicates across when duplicating a bug with dupes, is in review, we should add a confirmation dialog in the web UI when trying to mark duplicate a bug that itself has duplicates. The thinking is that undoing a mistake could be quite time consuming, so a "Are you sure you want to mark this bug and all it's duplicates as duplicates of XXX?" will call attention to the change.

This dialog will only be enabled for a bug that itself has duplicates.

Deryck and I discussed this on LP and it would seem that some sort of limitation should be placed on who can do a multi-dupe move as the possibility of mistakes have a much greater impact than a single bug move. I created bug 591749 to allow for mass deduplication of bugs in case a mistake is made.

Micah,

After doing this work now, I don't think we need the limitation on who can use this. The warning is nice, and it's easy to follow the trail of dupes, i.e. the activity log works as it should with multiple changes. There could be problems, but I already have a lot of time in the work and I don't want to block landing on this extra functionality. I'll land on edge as soon as I can, and we'll watch it closely before rolling out to wider audience.

Cheers,
deryck
