Which Umbraco version are you using?
16.3.4
Bug summary
It seems something recently broke rendering of blocks in block list inline mode?
Recently we had links blocks rendered inline, but it seems these no longer render.
In console I see a few errors.
At least it worked in 16.2.0
#20404
It is worth mentioning the block has properties directly under a single tab.
Specifics
No response
Steps to reproduce
Add a block list using inline mode and noticed expanding block doesn't render properties.
Expected result / actual result
No response
