-This file fixes a bug in Chrome where blurring / moving selection away from the composition
+This block undoes the addition of div.onbeforeinput = () => {}. This is very, very
+gross, but Slate uses the presence of this handler (Added in Chrome 105) to activate a
+new version of it's event handling, which doesn't quite work properly in our old version
+of Slate: https://github.com/ianstormtaylor/slate/issues/5108#issuecomment-1297591129
+
+Since this was added to Chrome in v105, we can be fairly confident nothing else needs
+it to exist, or will similarly fall back to document.addEventListener('beforeInput')
+
+One day, we will update Slate to the latest version, but 0.50.x is effectively a rewrite
+and we have many custom plugins that need to be re-built and re-tested.

+This block fixes a bug in Chrome where blurring / moving selection away from the composition
 dropdown "commits" the composition but does NOT fire a textInput event to tell Slate.
 
 To reproduce the bug, enter Japanese editing mode, type "korewa" and then exit the composition
