I added a Paragraph (multiline text field) to my issues.

It says the field supports rich text, bold, colored text, etc. but whatever I tried to insert rich text failed.
I am trying to set the field value to something like :
Some bold text
Some standard text
By manually editing the field on the issue, or via automation. Both fail.
If I try to set the field value with automation like
*Some bold text*
Some standard text
When viewing the issue, I can see the 2 asterisks (*) around "Some bold text" but the text is not set to bold. The same happens when editing the field on the issue itself, and the same happens with other formatting such as color, etc.
