Typescript ambiguous regexp highlighting with normal division #3874

In typescript (or javascript as well), regexp is part of the language and can be expressed like so

const myRe = /d(b+)d/g;

And we have the following rules to match it:

- constant: "/[^*]([^/]|(\\\\/))*[^\\\\]/[gim]*"

If you have the following

//My use case:
vec2.set(outVec, width / 2.0, height / 2.0);

//Or simply
const abc = 10 / 5 / 2;

Looks like this

Funny enough, javascript doesn't have this problem since the line is commented out. Due to issue #901

But then it got a different issue, somehow (issue #2820), which got fixed later.

A proper fix (if we want to highlight it) requires lookahead as mentioned by @zyedidia in #901 ,unless there's a way to specify a pattern that excludes that type.

@JoeKar, any thoughts?
