Any progress on the ACR 7.3+ Bridge repeat thumbnail extraction problem?

Question

Any progress on the ACR 7.3+ Bridge repeat thumbnail extraction problem?
It was very good news that the cropped lens-correction repeat extraction bug was fixed in 8.2, but this newer problem, surfacing in the ACR 7.3 update (and still present in 8.2), is causing a bigger headache than the older bug for some users of Bridge.
Unfortunately, I have been unable to identify a trigger for the condition, which is proving very difficult to recreate reliably, other than it very definitely being introduced with ACR 7.3. Adobe's Steve G told the Bridge forum that the 7.3+ problem had been recreated by Adobe, and was being investigated along with the other (now solved) problem. Has any progress been made? Or is it still a mystery?

Been there, done that:

They know about it, they just don't know how to recreate it.
Best thing we can do is reliably recreate the fault. My workaround is to only enable Lens Profile Corrections when necessary, as it is a combination of that and some other factor(s) which seems to trigger it.
If you read all the discussions, you'll see that there are two bugs which produce the same symptoms. One introduced in probably ACR 6.1, whichg was fixed in 8.2; and the other was introduced in 7.3 and is ongoing.
