fast/text/selection/khmer-selection.html is failing/flaky on Win

Project Member Reported by pdr@chromium.org, Jul 7

Issue description

This test started failing at:
New inline text rendering to support ligatures
https://chromium.googlesource.com/chromium/src/+/129e4ea0be58c7d1c20be2c719b66b794d3c983f

Test:
https://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Ftext%2Fselection%2Fkhmer-selection.html&testType=webkit_layout_tests

Example failure:
https://test-results.appspot.com/data/layout_results/WebKit_Win10/37552/layout-test-results/results.html

The results actually seem flaky in the non-selected text, which is surprising. I'm going to suppress the failure for now, but this should be investigated.
 
I think this test has always been a little flaky on Windows, even before your patch. It looks like your patch picked up the flaky baseline which causes the test to fail 90% of the time (instead of 10% as before).

The flakiness looks like an issue getting the font for the teletype text between <tt> tags. WDYT of removing the <tt> tags from the test since they are unrelated to the actual test?
