Blocking fonts breaks only one menu

[xundeenergie]

Describe the bug

I have browser.display.use_document_fonts set to 0 in my firefox as security-feature. This breaks only one menu. All others are working as expected. Look at the screenshot.

Setting this to 1 the menu is correct.

Steps to reproduce (if necessary)

Steps to reproduce the behavior:

1. Go to 'about:config'
2. Set browser.display.use_document_fonts to 0
3. Go to writefreely and hover over "Drafts" in writing-mode

Expected behavior

The fonts in this menu should be the same as in every other menu in writefreely too.

Application configuration

• Single mode or Multi-user mode? Multiuser
• Database? [mysql/sqlite] mysql
• Open registration? [yes/no] no
• Federation enabled? [yes/no] yes

Version or last commit: v0.12.0

I found, the broken Menu has this CSS-Styles (from Firefox developer tools)
`header nav#user-nav a {
font-size: 1.2em;
font-family: 'Open Sans','Segoe UI',Tahoma,Arial,sans-serif;
}
header nav#user-nav a {
font-size: 1.2em;
font-family: 'Open Sans','Segoe UI',Tahoma,Arial,sans-serif;
}
.material-icons {

font-family: 'Material Icons';
font-weight: 400;
font-style: normal;
font-size: 24px;
display: inline-block;
width: 1em;
height: 1em;
line-height: 1;
text-transform: none;
letter-spacing: normal;
word-wrap: normal;
white-space: nowrap;
direction: ltr;
-webkit-font-smoothing: antialiased;
text-rendering: optimizeLegibility;
-moz-osx-font-smoothing: grayscale;
font-feature-settings: 'liga';

}
`

the other menu haas only this CSS-Style
header nav#user-nav a { font-size: 1.2em; font-family: 'Open Sans','Segoe UI',Tahoma,Arial,sans-serif; }

Thanks for the report, @xundeenergie. Do you have any resources on what security improvements that browser feature gives you? From my own knowledge, I'm not sure of why someone might be motivated to disable icon fonts, and hence if it's worth supporting that browser feature in the near term.

I'll close this now, but please feel free to respond whenever you can.
