HTMLParser should ignore not native HTML attributes

Attributes not native to HTML (such in vue or react & attributes with non completly string values) should be ignored by HTMLParser completly instead giving back as classes.

<input :checked="isCheckbox ? value : undefined" />
<div class={isRead ? "red": "green"} />

running with following,

const parser = new HTMLParser(text);
const classes = parser.parseClasses();

will give back the classes

isCheckbox ? value : undefined
isRead ? "red": "green"

Yes, that’s exactly what I mean 😛. We can have a block list and add more as we go.
