/* !important matters here: every previous attempt at this fix assumed the
   problem was about *when* this class gets applied, but a plain CSS class
   rule for `transform` can never win against an inline `style="transform:
   ..."` set directly on the same element, regardless of timing. The
   library's own "stretch" sizing plausibly sets its own inline transform
   while it's still settling into its final pixel size, silently
   overriding this correction for as long as that's present — which would
   explain "wrong initially, fine after any interaction" far better than
   any timing theory does, since the fix in that case isn't about when we
   apply this, but about making sure it can't be overridden at all.
