RichText "AllowedFormats" not working for links

[Ipstenu]

Describe the bug
When using a custom block that has allowedFormats={ [ 'core/bold', 'core/link', 'core/italic', 'core/strikethrough', 'core/text-color' ] } the one for core/link does not show up.

To reproduce

1. Make a custom block using RichText
2. Set allowed formats to include 'core/link'
3. Add the block
4. Check the toolbar -- no links

Expected behavior
Links should remain a functional item

Screenshots

Editor version (please complete the following information):

• WordPress version: 5.4.2
• Does the website has Gutenberg plugin installed, or is it using the block editor that comes by default? Both
• If the Gutenberg plugin is installed, which version is it? 8.4.0

@Ipstenu Do you have Yoast SEO active on the site? See the linked issue or Yoast/wordpress-seo#15617.

Oh yeah that'd be it. That sucks. It broke my plugin and there's really no way for me to check "If you have Yoast SEO..." and call a different JS or anything :(

I can put in yoast-seo/link but now their plan is to take-over the link component and that sounds like it would really mess with people who have a plugin break on what appears to be a core component without an easy way to figure out where the code wasn't called from

@Ipstenu I completely agree. We've asked for the core component to be filterable several times and even submitted pull requests for that, those were denied so far. We want to fix this in a better way in core, so far the Gutenberg team doesn't allow us to.

[Ipstenu]

So perhaps this ticket should become "Make core/link and other components filterable so we don't kick the break can down the line" :)

Closing this issue as adding link extension capabilities is being tracked in #11599.
