Hmm, seems like this doesn't have very good coverage, and no coverage in chrome outside of textboxes

source: https://developer.mozilla.org/en-US/docs/Web/CSS/user-select

Would probably want a solution that works a bit better with chrome at least.

hi @d-pollard, i didn't understood your request,

1. do you want me to add css vendors for better support
2. or you reject the idea and tell me to look for another solution?

if it's 2) can you please look at this conversation, they say 80% coverage is enough
and chrome does support user-select: all looking in MDN

please see the discussion in this issue:
#1893

Thanks

From MDN:

This doesn't have any effect on content loaded as chrome, except in textboxes.

I'm not outright rejecting this, but I would like to see full support, especially for Chrome since its market share is ~70%

[adico1]

@d-pollard I tested this in chrome and clicking CODE once select the text with that style (it was also tested by the people in the reported issue).

I think the note in MDN is misleading.
scroll down to support and you'll see that chrome is supported.
