Add support for custom onSplit, onSplitMiddle #47806
Description
What problem does this address?
There are occasions when we would like to modify onSplit behaviour.
In the example below, we want the split Heading to be a paragraph.
We had to use patch-package to make the above change:
What is your proposed solution?
Currently, onSplit is a prop of the RichText child of BlockEdit and we don't have a way to manipulate it.
Request - allow custom onSplit, onSplitMiddle behaviour.

Hi @kosiew! I recommend using a ref to override the keydown native event and use
event.preventDefaultto prevent RichText default behaviour. Note that this won't work with React events atm.youknowriad commentedon Oct 22, 2026
Thanks for the report, @kosiew! The example here is now core behaviour: since #61891, splitting a Heading turns the second half into a paragraph (the default block), so the patch shouldn't be needed anymore. More generally, splitting moved out of RichText into the block editor store in #54543 and is now opted into with the
"splitting"support in block.json, which is why the RichTextonSplitprop was deprecated rather than extended. Closing thanks.
