Do not highlight HTML entities

[kkoomen]

The current highlighting for colors should not highlight the color when prefixed with the & character. I suggest to add a look-around here by optimizing the regex to:

const colorHex = /(?<=\W|&|^)((?:#)([a-f0-9]{6}([a-f0-9]{2})?|[a-f0-9]{3}([a-f0-9]{1})?))\b/gi

(The above adds & to (?<=\W|^)). See regex101 for working demo.

@chemzqm Can you merge this?

It doesn't fix the highlight.

@chemzqm Sorry, you should use this regex (demo):

const colorHex = /(?<!&|\w)((?:#)([a-f0-9]{6}([a-f0-9]{2})?|[a-f0-9]{3}([a-f0-9]{1})?))\b/;

I thought it already used negative-look-behind, but it didn't, so I used that. Makes more sense in this case.
