Ok, this is the second issue you created without ready to run reproduction code. As mentioned in the first one, we will not be looking at this before it is complete. Standard reply follows. If I were you, I'd focus on getting the reproduction code for your earlier report in place instead of opening another incomplete one...

Please supply us with ready-to-run reproduction code in the form of something we can copy/paste, a (zipped) project structure or a GitHub repository.

We do not have capacity to craft or compose a reproduction for every issue that gets raised.

If no code or repository is provided, this issue will be closed in 3 days

Help us to help you. Thanks.
