23 /*
24 We want to check that bidi is detected correctly. So, we have a reference
25 document where ltr is set explicitely with <bdo> element. Then, we compare
26 it with test document.
27
28 In mozilla, once bidi has been detected in a document, document always
29 consider it's in bidi mode. So, if one fragment enables bidi correctly, and
30 we create or update a fragment in the same document, that operation may not
31 enable bidi by itself, but it will not be detected. So, we need to have new
32 document for each test.
33
34 So, instead of many diferent reftests, this mochitest implements a
35 reftest-like. It creates reference text fragments in reference iframe, test
36 text fragments in test iframe, and compare the documents. Then, it reloads
37 test iframe. Reference iframe does not need to be reloaded between tests.
38 It's ok (and maybe, desired) to keep bidi always enabled in that document.
