Bug: Error handling background color in HTML snippet browser when changing theme

[KseniyaKerzhner]

Summary

When HTML snippet is opened, when switching from light to dark theme, the browser background becomes dark and the text is not visible. By default, the text in HTML is always black if there are no styles.
When the page is refreshed, the background is light again.
I suggest to make it so that the browser background in HTML snippets does not change and is always white.

The error is reproduced only when opening from the light theme for the first time or after reloading from the light theme.
If you just switch from dark to light theme, there is no error.

The JS snippet handles it correctly, the background in the dark theme is always dark because it's a console and the font is automatically adjusted there.
