Description

Font size for PR/issue comment is incorrect. It is using 16px inherited from .markdown class when it should be using its own overridden 14px. The issue occurred between 58cd55d (known good) and 2b2eb5d (known bad) but since half the commits have broken CI run I can't really test them properly without setting up full development environment.

See this try page for example: https://try.gitea.io/ChristopherHX/actions-on-gitea/pulls/2

On v1.15.6 this is handled by (generated code):

.repository.view.issue .comment-list .comment .content .markup {
    font-size: 14px
}

On broken version we can see this instead:

.repository.view.issue .comment-list .comment>.merge-section .markup {
    font-size: 14px
}

Screenshots

Bad (current):

Good (simulated):

In addition it seems that the button Update branch by ... has lost its styling too (should be right of the text, not below it).
