This line specifically causes the regression:

    window.getSelection().setBaseAndExtent(textChildNode, newCaretPosition, textChildNode, newCaretPosition);

How, I don't know. I also don't know how to investigate any further, so, perhaps we should just not call that on blur specifically since is isn't needed in that case anyway.
