Prevent problems with closure running after typescript.
This fixes two incompatibilities between shady-css-parser
and browsers.
1. If the css is missing a closing brace like
div { color:red
then Shady drops the last rule, but browsers keep it.
2. If a css ruleset has an empty selector like
/*empty*/ { color: red }
div { color: blue }
then Shady discards the { } and produces this:
color:red;div { color: blue; }
which has an entirely different meaning.
Browsers parse the empty-selector block, but then ignore it
as invalid.
For this case, we could either make Shady keep the block
or drop the block. I decided to keep the block, because
Shady generally passes through many other not-quite-valid
css text that browsers would ignore.

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for all the commit author(s) or Co-authors. If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google. |
This fixes the scenario where extra semicolons are immediately
followed (without whitespace) by a boundary token such as '}'.
For the ruleset: .foo{bar:baz;;}div .qux{vim:fet;}
Shady treats the first `}' as an extra token and adds div .qux rule
under the .foo selector.
Fix parsing for minified css with extra semicolons
The test case that is failing currently is
.foo{font-weight:300;@charset "UTF-8"}.bar{width:100vw;}.Expected result: .foo{font-weight:300;@charset "UTF-8";}.bar{width:100vw;}
