Not all CSS is applied with latest version of pydata-sphinx-theme

[lucaspcamargo]

Describe the bug

When I regenerated my website a bit earlier today... I expected it to look the same as always.

However, some CSS fails to apply. I see a blueish background color, purple link underlines from pydata-sphinx-theme, and larger icons.

Maybe something changed with the latest version of pydata-sphinx-theme which is breaking the latest version of this theme.

Reproduce the bug

I believe that regenerating a page with the latest version of pydata-sphinx-theme should be enough to reproduce the issue.

When I add pydata-sphinx-theme==0.13.3 to my requirements file, as a current workaround, the issue vanishes.

Same issue here for a documentation hosted on Read The Docs. Adding pydata-sphinx-theme==0.13.3 before sphinx-book-theme in the requirements file solves the problem.
