Hitting "delete" on an empty slate block does not delete the block

[tisto]

StR

• as admin
• create a new page
• hit return on the title block to create a new empty slate block
• hit delete (back on mac)
• -> I'd expect the block to being deleted (like on draftJS)

@tisto Weird, I've just tested on https://volto.kitconcept.dev/images/edit from Windows and this works. Maybe a MacOS quirk? I have a macbook somewhere, I'll see if I can replicate it there.

The "delete empty block" in slate only works if the next block is a slate block, as the operation is to "join with the next block".

volto-slate/src/blocks/Text/keyboard/joinBlocks.js

Line 121 in 41ae74e

if (data?.required || otherBlock?.required || otherBlock['@type'] !== 'slate')

This is in line with the delete operation in Word, most evident if you have some content on that line. I assume all text on that page was produced with slate?

I've made a test on:
https://volto.kitconcept.com/edit
and https://volto.kitconcept.dev/edit

I've concluded that Draftjs at least on Ubuntu 20.04 with Firefox 93 behaves worse than Slate currently does
with regards to delete key behavior.

There are probably some delete behavior changes that we might want to make in order to ensure
that delete key works as you've mentioned but right now this is an universal issue and not only related
to Slate editor.
