Bug description

When using custom elements implementation of swiper in angular 'injectStylesUrls' option has no effect - styles are not applied. Using the same styles, but provided via injectStyles works fine. In provided stackblitz you can switch between injectStylesUrls and injectStyles by commenting part of code.

If you open devtools you can that swiper is actually downloading provided stylesheet, but styles do not get applied anyway.

Expected Behavior

Same styles that can be applied via 'injectStyles' option should work with 'injectStylesUrls'.

Actual Behavior

Styles provided via 'injectStylesUrls' do not get applied, even though swiper gets them (what you can see in network tab in devtools)

Swiper version

9.3.1

Platform/Target and Browser Versions
