[webvtt] [IR] settings line test failing (#468)

gkatsev has just created a new issue for https://github.com/w3c/webvtt:

== [IR] settings line test failing ==
The [settings line test](https://github.com/web-platform-tests/wpt/blob/master/webvtt/parsing/file-parsing/tests/settings-line.html) is failing across the board.
In Chrome and Safari a value of `.5` and `5.` are parsed as `0.5` and `5.0` respectively. The spec specifically calls numbers beginning and ending with `.` as invalid values.
Chrome and Safari do not support line align, which is being marked as at risk in #460 and may warrant splitting out line align tests from regular line tests.
Safari also defaults to the value `-1` rather than `auto` and a very large negative number is set to zero rather than Number.MIN_VALUE as the test suggests.
Firefox is failing due to it's very strict parser.
