Update for changes in OOjs UI (Ib40e3477)

I can't make head or tails of this code. Adding this line seems to
prevent big regressions, but the sizes of things still change very
slightly, inexplicably. Various "reset" styles make this really hard
to debug and this is probably good enough, so I won't bother.

Bug: T91152
Change-Id: I3f61231162f2963cc16cee9d0249dbb56fb84cf0
