Issue description

When exporting a variable, you can usually add a custom description to it by adding ## this variable does that above it, and when hovered over it shows the description. (like so)

But when you export a custom category, the variables under it say "no description." (like so)

Here's the code

Steps to reproduce

1. export a category
2. add a variable below it
3. add a custom description to said variable

• Duplicate of GDScript documentation comments: description tooltips are omitted when applied to @export variables with multiline arguments, as well as @export_category #78934.

Thanks for reporting the bug nonetheless!
