There appear to be some cases where I observe different styling behavior on each refresh. I am filing in Core :: CSS Parsing and Computation as it feels like some styling data is being cached or there's a race somewhere. Firefox 67.0a1 (2019-03-10) macOS 10.14.3 STR: 1. Load https://styling-toggle-firefox.glitch.me/ with DevTools closed 2. The displayed output might look like either attachment A or B * For me, a regular refresh (Cmd-R) usually triggers variant A, but a hard refresh (Cmd-Shift-R) triggers variant B, but it is not consistent 3. Opening the DevTools inspector may also affect styling 4. If you are seeing variant A (letters raised), you should be able to inspect an element with class `mx_BaseAvatar_initial` and toggle any property off and back to on, which seems to force a style update and changes to variant B (letters centered) * If you try this experiment many times, you should close DevTools before refreshing. Simply having DevTools open affects cache timing and may cause the issue to not appear. ER: The styling output should look the same in all cases. AR: There seems to be a race somewhere that affects styling on initial page load.
