linkifyText throws a DOMException if a link is inserted inside a text node

open Demo.html
open DevTools
type "ww" into the text editor
press the left arrow key once
type a space
type "www.google.com"
type another space
see the error pop up in the console:

Uncaught DOMException: Index or size is negative or greater than the allowed amount squire-raw.js:1659

the reason are the following lines:

Squire/source/keyboard/KeyHelpers.ts

Lines 127 to 133 in a8cd95a

    
           const startOffset = selection.startOffset; 
        
           textNode.data = data.slice(endIndex); 
        
           if (selection.startContainer === textNode) { 
        
               const newOffset = startOffset - endIndex; 
        
               selection.setStart(textNode, newOffset); 
        
               selection.setEnd(textNode, newOffset); 
        
           }

I'm not sure what the exact bug is here.

Thanks for the report!

	const startOffset = selection.startOffset;
	textNode.data = data.slice(endIndex);
	if (selection.startContainer === textNode) {
	const newOffset = startOffset - endIndex;
	selection.setStart(textNode, newOffset);
	selection.setEnd(textNode, newOffset);
	}
