[Feature] Ability to delay or re-apply styles (gmail)

[michaeldrob]

Is your feature request related to a problem? Please describe.

In Gmail, styles get applied before most of the DOM is loaded and somehow since it's all dynamic, the style do not take effect until you turn them off and on again

Describe the solution you'd like

I would like a "timer on refresh" that would delay application of styles by some amount of time. In the case of Gmail, a second or so would likely be enough, but better make it configurable.

Additional context

If the extension can just detect load instead, that would be even better
