Bold with underline characters

Earlier today I was trying to write something where I wanted two characters to be highlighted. I felt this didn’t contrast them enough so I thought I’d check if ziggit supports underlining. There’s no underlining support on the editor bar, but CTRL+U actually worked. But not as intended.

Steps to reproduce:

Type anything.

cake

underline just the first letter by highlingting and CTRL+U

cake

Now bold.

**c**ake

Now either post or switch from the markdown editor to the standard editor. and of observe the c has ** on both sides.

Expected behavior: c is emboldened and underlined.

Ditto for underlining/bolding **all but the las**t letter of a word, but it’s totally fine as long as the whole word is captured.

edit: better example for clarity
