Web Components have definitely failed.
If such a "universal rich text edit" web component comes out, have web components then succeeded? Then failure isn't such a permanent state as your comment implies, rather an indication of work yet to be done.
Unless you'd like to clarify more, your comment seems to me like you're flinging mud without being able to back it up. What's the reason for that?
Of note, Trix has been using the `customElements` standard since forever: https://github.com/basecamp/trix/
There's also slate, the (old!) tinymce, umm... I know I've at least experimented with a good couple more I can't recall.
And, on the topic of components I wish existed (anywhere - react, vue, angular, etc - anything), I've been searching for a good rich multiselect for a long time! If you know of any please let me know :)
Select2 [1] has been around forever but it's always worked out pretty nicely for me.
It's a jQuery plugin, so it's somewhat out of vogue these days, but it's trivially easy to wrap it in a component to make it play nicely with Vue (in fact, the Vue documentation uses it as the example for writing wrapper components [2]). I imagine something similar can be done with React, Angular, etc., though I'm not too familiar with the process there.
I think (but this is my interpretation) that GP meant to assert by saying "Web Components failed" that no such component will ever come out, because Web Components cannot properly solve that use case. I haven't delved into it deeply, but my intuition is that, indeed, quite a lot of ceremony would be needed to integrate such a component into a larger web app, regardless of whether you use a framework or which one.

Sometimes I really, really dread this whole "frontend" related churn, tooling, javascript and it's quirks. I looked at Flutter recently wondering - maybe this is the answer? But this probably is just another turn of the wheel, it was attempted already in the past with adobe air/flex and many other projects.
Maybe reason for this is that programming and whole IT is very young craft, mere child's play compared to different industries like for example construction which has thousands years of history, trials, successes and errors.
We keep making this mistake of wanting to use what's available instead of coming together to build something better, so we waste MILLIONS of collective hours because we're dumb.
