Escaped ( in selectors breaks output

[guivr]

Hi! Thank you so much for this.

I found a bug when using Tailwind.

Selector:
.mb-\[max\(-70\%\2c -23rem\)\]

returns token:

[
	{
		"type": "class",
		"content": ".mb-\\[max\\(¶¶¶¶¶¶¶¶¶¶¶¶¶¶¶¶",
		"name": "mb-\\[max\\(¶¶¶¶¶¶¶¶¶¶¶¶¶¶¶¶",
		"pos": [
			0,
			27
		]
	},
	")\\]"
]

This selector isn't a proper CSS selector to begin with, but Parsel should at least throw or handle this case gracefully.

The root cause of the bug is the escaped parens, in fact even a selector like .\(\) reproduces the issue, and .\( causes an actual error (Opening paren without closing paren), which makes me think they are somehow interpreted literally in the regexes.

This is definitely a bug, thanks for catching it!

@jrandolf Special characters can totally be a part of class or attribute names, they just need escaping.
