certain bold & italics broken after leaving Goyo

[daveriedstra]

issue

When using a plugin for markdown syntax (such as vim-markdown or vim-pandoc-syntax), leaving Goyo removes formatting for *italic* and **bold** elements (and underscore variants), though the asterisks / underscores remain concealed properly. Other bold and italic formatting (such as # headings) works, which makes me think this is somehow related to concealing.

reproduce

1. open or create a markdown file with some _italic_, __bold__, *italic*, or **bold** formatting

2. enter Goyo mode

3. observe formatting is correct

4. leave Goyo mode

5. observe formatting lost

6. enter Goyo mode

7. observe formatting still lost

I also have this problem in NVIM 0.5.0.

Confirming that the issue with conceal being 'reset' is also happening in Vim 9
