Shipping Yosemite. Release, WK1, run after editing/selection/move-by-character-brute-force.html.
Occurs even after applying the workaround in https://bugs.webkit.org/show_bug.cgi?id=140253
"Shipping Yosemite" = 14B25
Same thing for tables/mozilla/bugs/bug113235-1.html
Same thing for tables/mozilla/bugs/bug8858.html
Same thing for fast/encoding/utf-16-big-endian.html
Same thing for fast/encoding/utf-16-little-endian.html
Similar for svg/custom/svg-fonts-without-missing-glyph.xhtml, but the test you need to run before it is fonts/font-fallback-prefers-pictographs.html
fonts/sans-serif.html is back to editing/selection/move-by-character-brute-force.html
The rest of the tests in this section, until the last two (media/controls-after-reload.html and media/controls-without-preload.html) don't seem relevant. Those two media tests are marked as always failing on Yosemite.
This smells like a single underlying issue.
