The [processing model](https://w3c.github.io/webvtt/#applying-css-properties) sets 'unicode-bidi' to `plaintext` which isolates paragraphs, and then sets 'text-align' to `start` for \"Start alignment\", and the behavior of CSS in that case does not match the description above.\r\n\r\nSee\r\nhttp://software.hixie.ch/utilities/js/live-dom-viewer/saved/3719\r\nand flip the value of 'text-align' between `start` and `end` (in Gecko or WebKit or Blink), to see what the effect of the processing requirements are.\r\n\r\nSo for start alignment, each line is aligned to the start edge for that line, which is separate from the **cue**'s \"paragraph direction\".\r\n\r\nMy understanding is that @r12a is happy with the effect of the processing requirements, so I suggest we fix the description here to match."}}
