| Test that HTMLDocumentParserFastPath correctly caches whitespace (newline + 0-32 spaces) when using innerHTML. This test does not check utilization of the cache. It just verifies that generated text nodes have the correct number of spaces once parsed and constructed into the DOM. There is currently no observable way to detect that the cache has been utilized, or a side effect of using the cache to detect. |
| |
| On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". |
