reproduce: create a

and use snippets <div here> and navigate the list. Crashes every time.

It seems to only happen on non-custom snippets like div, span, h1 etc but anything custom from my html snippets (ultisnips) is fine

I've tried removing my snippets file entirely (html.snippts), it doesn't have any effect, still crashes

using :healthcheck I was able to find where I had a duplicate binding over<leader>a and remove it, and the issue resolved
