We are tired of rebaselining layout tests that are not related to spell checking, but have to be rebaselined because of the appearance/disappearance of misspelling markers in their pixel results.
A typical example is "foo", which appears in almost all layout tests. Every time we do some change to the spell checker, the misspelling markers appear in some tests and disappear in some other tests, while none of these tests are for spell checking.
We should make sure that we see spelling markers in the pixel results only when we are intentionally testing the spell checker. For this purpose, we should ensure that MockSpellCheck's list of misspelled words contains only some very special strings that cannot appear in other tests.
