Lexical version: commit 4a43cb027f55718d6d32cc7fb8e7ec31adf59d2e

Steps To Reproduce

1. Type a macOS text replacement and press space.

Link to code example:

The current behavior

The caret ends up before the space.

The expected behavior

The caret ends up after the space.

Impact of fix

This happens for every macOS text replacement. This behavior does not match expectations, leading to users who type fast missing spaces (or, rather, typing before them). This is arguably the fault of how Chrome and Firefox fire the Space beforeinput event before the replacement event (Safari doesn't, so it's fine).
