Remove DOM dimension noise and fix document.fonts to prevent site crashes

DOM element dimension noise (offsetWidth/Height etc.) broke complex web apps
like Discord by returning fractional values where integers are expected.
Removed entirely — measureText noise is sufficient for font enumeration.

Changed document.fonts.check() to return true (uniform response) instead of
false, which caused font loading logic to hang in apps waiting for fonts.
