Remove html from display

[lpatiny]

There is an issue with the string displayed on the spectrum is that it can contain <sub> or <i> and <sup> that is displayed rather than rendered.

I guess the faster way to solve this issue is to remove the html code when overlaying over the spectrum. I guess in the future we should again consider foreignObject but we would loose compatibility with inscape. Not sure about adobe illustrator if somebody could test it:

To remove the html before display over the spectrum (Copy the assignment should still have the html) can be something like:

input.replace(/<[^>]+>/g, '')
