Ctrl-End followed by Ctrl-Del makes the vello_editor example panic

[PoignardAzur]

Not much else to say. Steps to reproduce:

• cargo run --bin vello_editor
• Press Ctrl-End (cursor goes to the very end of text).
• Press Ctrl-Delete.

The example panics with this message:

thread 'main' panicked at /rustc/f6e511eec7342f59a25f7c0534f1dbea00d01b14/library/alloc/src/vec/mod.rs:2207:36:
slice index starts at 1120 but ends at 1119
