They'll let us know in that thread when it's fixed.
I recommend reporting Beta bugs using the handy Comment icon in the upper right of the PR window:
Click on this, and it includes "report a bug" and gives you the option to copy your system info for pasting into the report.
This includes the Build you are using, which is important. Beta build update almost daily, and a variety of bugs come, get fixed, and are gone within days.
