Several ES6 additions are only available in strict mode. Example:
> SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
Strict mode was also enabled in a few of our files already, and it is a good thing to have anyway.
- Data should be handled as is and only do the escaping on
the view/template or wherever it is used and escaping is necessary.
Keeps things simple and the focus of escaping values in the right place.
- Remove topic capitalization
- For long topics: hide overflow and add a title to topic span
- Also, simplify the code a tiny bit.
