That’s unfortunate.
Would you be so kind as to have a quick look at this sandbox to see if the same thing happens? The Hello World post has a default section/container block.
I have not been able to reproduce the issue this far.
Luckily, I was able to replicate on the sandbox. Here’s the test page: Test – cwiclydemo
Currently it looks as intended. If you Regenerate Global Styles CSS, you’ll see the styling disappear.
To get it back, go into a page and click update.
This can be repeated many times.
Possibly the missing piece here is that I needed to activate the “Remove Container Block Display Properties” setting for things to break.
Thanks for taking the time to look at that and guiding me through it.
I can finally confirm an issue with layout properties when editing global block elements.
EDIT: also confirming this isn’t related to the “Remove Container Block Display Properties” setting
I have added it to the bug tracker. A fix should be available in the next update.
