Invalid native attribute names

[yo3jones]

Getting this browser error at runtime:

Uncaught DOMException: Failed to execute 'setAttribute' on 'Element': 'aria-live\' is not a valid attribute name.

It looks like the escape of the $ is not necessary, which leads to a trailing back slash.

Example can be seen in iron-a11y-announcer

<div aria-live\$="[[mode]]">[[_text]]</div>

will work if the \ is removed:

<div aria-live$="[[mode]]">[[_text]]</div>

Is this actively being worked on?

Probably not yet as it was opened 20 hrs ago. I'm sure it will be in the near future unless you want to put out a PR to fix it 🙂

Added Polymer/polymer#5060

I can see this using .raw in Polymer's html-tag may be an issue in every other place involving a $ or escaped backtick characters etc.

Update: This is actively being worked on in the context of Polymer/polymer 2.next and upcoming 3.0 prerelease version as we speak. Modulizer output is still going to emit the escaping for forseeable future for all dollar signs, backticks and backslashes.
