This patch changes a test to non-quirks mode, that hits
not-defined, non-interoperable line-height quirks.

When all characters on a line is above baseline or below
baseline, by applying e.g., 'vertical-align: 1em' or
'line-height: 0':
* Blink/WebKit assumes the baseline is part of line-height,
  except for atomic inlines.
* Gecko does not include baseline to line-height.
* Edge always include baseline to line-height.
* This problem appears only in line-height quirks mode,
  because otherwise we have a strut that includes baseline.

It's not hard to fix this, but does not seem to worth. We can
revisit if webcompat proves this is necessary.
