When a test fails on first try, some bots retry it with pixel testing enabled. For tests that don't have pixel results checked in, this results in a "TEXT MISSING" failure (TEXT on first try, MISSING on second try). These are not reported as true regressions by run-webkit-tests, buildbot, or dashboard. See e.g. https://build.webkit.org/builders/Apple%20Yosemite%20Release%20WK2%20(Tests)/builds/173 - there are 6 editing/selection tests that fail, but the test run is not red.
