For that: * Remove support for caching resizer styles, since they don't seem common enough to warrant it, unlike all other scrollbar parts. * Make scrollcorners have pointer-events: none with overlay scrollbars, so that the setup works / we can assert that if we have overlay scrollbars then we don't care about the pointer-events value on ancestors.
