Fix a WPT test relating to `content-visibility: auto` and
content-relevancy. This test attempts to change the relevancy of content
by blurring it, but relevancy also depends on selection. Apparently,
Gecko differs from other browsers in that `blur()` is not moving the
selection as well. The fix is to simply focus another element which will
update both focus and the text selection.
