I've been running a suite of my few hundred test cases and I can confirm that rolling back from TC15.51 to TC15.49 / TE15.49 is working for me.
For reference, the framework we built uses xpath identification for objects (and we do not do any name mapping because that is a mess). I wanted to put that out there since I have no idea how namemapping is impacted at the moment.
These are the browser versions and test complete versions I tested and the results of my testing.
| TC 15.47.4.7 | TC 15.49.6.7 | TC 15.50.3 | TC 15.51.47 |
Chrome 113.0.5672.93 | Working | Working | Not Working | Not Working |
Edge 113.0.1774.35 | Not Working | Not Working | Not Working | Not Working |
I hope this helps anyone who is stuck at the moment.
