Simple Table in a Quote Block: inserting a list into a table cell removes the table

If you have a simple Table inside of a Quote Block, you can, for example, still put a Heading into a cell by using the Slash command.
But try the same with a numbered list, or a bulleted list - the whole table becomes replaced with the list.

As a workaround, it is possible to add such a list into a table that's outside of the Quote block and then move the whole table into the Quote block. That works.
