Bug 53846 – Webkit removes empty text nodes and does not allow creating such ones.

• Component: DOM
• Status: RESOLVED CONFIGURATION CHANGED

[Alex]

Here's a code example:

var a = document.createElement( 'div' );
var b = document.createTextNode( 's' );
a.appendChild( b );
document.body.appendChild( a );

And code line 'b.deleteData( 0, 1 )' will cause webkit not only to remove the text node's data, but a text node. I develop an online editor project and this behaviour for me is very disappointed. Opera and firefox( gecko ) treat empty text nodes normally.

I am able to reproduce this bug in Safari 15.6 on macOS 12.5 using below JSFiddle from test case of Comment 0:

Link - https://jsfiddle.net/arpL7twq/

Open and in console type - 'b.deleteData( 0, 1 )' without quotes and then hit "Enter".

Safari 15.6 will keep on showing 's' text node while Firefox Nightly 105 and Chrome Canary 106 will get rid of text node.

I am changing status to "New". Thanks!

Test case

All browsers agree now (Text node is retained).
