Fixes#11628
PR #6389 caused bug #11628, which is a regression, as it had already
been fixed in #4441
It is likely that some things have changed because [Lexical had recently
made improvements](https://github.com/facebook/lexical/pull/7046) to
address selection normalization.
Although it wasn't necessary to resolve the issue, I added a
`NormalizeSelectionPlugin` to the editor, which makes selection handling
in the editor more robust.
I'm also adding a new collection to the Lexical test suite, intending it
to be used by default for most tests going forward. I've left an
explanatory comment on the dashboard.

Looking at #11628's video, it seems users also want to be able to
prevent the first paragraph from being empty. This makes sense to me, so
I think in another PR we could add a button at the top, just [like we
did at the bottom of the
editor](https://github.com/payloadcms/payload/pull/10530).
Lexical tests comprise almost half of the collections in the fields
suite, and are starting to become complex to manage.
They are sometimes related to other auxiliary collections, so
refactoring one test sometimes breaks another, seemingly unrelated one.
In addition, the fields suite is very large, taking a long time to
compile. This will make it faster.
Some ideas for future refactorings:
- 3 main collections: defaultFeatures, fully featured, and legacy.
Legacy is the current one that has multiple editors and could later be
migrated to the first two.
- Avoid collections with more than 1 editor.
- Create reseed buttons to restore the editor to certain states, to
avoid a proliferation of collections and documents.
- Reduce the complexity of the three auxiliary collections (text, array,
upload), which are rarely or never used and have many fields designed
for tests in the fields suite.
