[WebCore] Debug assertion fails in needsTikTokOverflowingContentQuirk

When navigating to
https://threejs.org/examples/?q=webgpu#webgpu_loader_texture_ktx2
in a Debug build of MiniBrowser we get following assertion:
```
ASSERTION FAILED: hasClass()
/Volumes/Shared/wk1/OpenSource/Source/WebCore/dom/ElementInlines.h(150) : const
SpaceSplitString &WebCore::Element::classNames() const
1 0x3051b5268 WebCore::Element::classNames() const
2 0x306d44168
WebCore::Quirks::needsTikTokOverflowingContentQuirk(WebCore::Element const&,
WebCore::RenderStyle const&) const::$_3::operator()() const
...
```
That seems to be caused by calling `Element::classNames` in `Quirks.cpp:2031`
without
first checking whether `Element::hasClass`, so I added the check to pre-existing
early exit conditions.
