LibWeb: Fix two problems where media queries didn't invalidate properly

There were two things going wrong here:

- Transformed text (via CSS text-transform) was not invalidated after a
  `@media` rule changed state.

- Removing the `style` attribute from an element didn't trigger a style
  update.

This fixes the regression in subtest 46 of Acid3.

Fixes #21777
