When I'm trying to use some "special" characters around the Polymer data bindings it does work, but the linter doesn't recognise the syntax. For example, if I use the starter kit to render the sample polymer-2-element, and after that instead of the default:
<h2>Hello [[prop1]]!</h2>
I add
<h2>Hello [[[prop1]]]!</h2>
<h2>Hello [[[prop1]]]!</h2>
it does work and shows something like this: https://i.imgur.com/7nkJGda.png
But my problem is that I have polymer lint in my build script and it fails because it returns these errors: https://i.imgur.com/027qxWf.png
LE: forgot to mention: if I add a space in between the first opening bracket and the data binding it does work.
I realise this is not a very serious problem, but I would like to know if anyone else found a solution to it, because I have had some other problems with HTML entities in Polymer that I had to work around and I'm curious if there's some fix I'm not aware of.
UPDATE: also forgot to mention that I am perfectly aware that I can wrap the property in a method call and have it return the padded value, but I was hoping for something simpler to write and easier to understand for anyone reading that code after a while.
