Consider dropping support for older Chrome (<=55)

[jodator]

What problem does this feature solve?

We've encountered a bug where Vue was removing a single DOM element from an editor component.

Namely this code:

0f2cb09

It removes any content inside a Vue component - event if it is not a text node. This is potentially risky behavior for complex components like CKEditor where the component expects that DOM is not changed externally. More info here: ckeditor/ckeditor5#2016 (comment).

What does the proposed API look like?

After reading the original rationale behind this change (#6601 (comment)) I'm not sure if Chrome 55 is still an issue as it was 2 years before.

Ideally, this code is not needed anymore but in a case that it is still needed then maybe an additional check for node type would be better.

Some specific older versions of chrome are supported, dropping the support would be a breaking change, we cannot do it.
If you have a boiled down reproduction without ckeditor of the problem, please open a new issue with it

Hi! Thanks for the clarification. Where can we find information about which versions of Chrome are supported? I guess that at some point in the future you're going to finally drop support for some really old versions, as it happens with every project from time to time. I wonder if it's possible for us to somehow track this decision so we can remove the workaround from our code once you'll clean up Vue's implementation.
