Flash of white when opening a new tab

[LoganJFisher]

Describe the issue or bug
When I open a new tab in my browser, there is a flash of white in a brief moment before nightTab properly loads in. I've tried different background options, but that doesn't affect it.

As someone who uses dark mode for everything, this flash of white is a bit disruptive.

To Reproduce
Steps to reproduce the behavior:

1. Open new tab

Expected behavior
No flash of white. A flash of black would be preferable if any flash at all is necessary.2

Screenshots

Desktop (please complete the following information):

• OS: Win11
• Browser Firefox
• Version 124.0.1
• nightTab version 7.3.0

Additional context
I have tried disabling Dark Reader, as I thought maybe that could be causing this. No effect.
