HTMLInputElement.setRangeText does not update text value

Would you be able to provide a reproduction case?

It seems it doesn't happen in all cases. It happens when an HTMLInputElement or HTMLTextAreaElement are disconnected.

There are actually two LayoutTests that already test this case:

* fast/forms/setrangetext.html
* imported/w3c/web-platform-tests/html/semantics/forms/textfieldselection/selection-value-interactions.html

LayoutTests/fast/forms/setrangetext-expected.txt

Check that setRangeText() on disconnected elements doesn't crash and has proper values.
element.value = '0123456789'
element.setRangeText('ABC', 0, 0, 'select')
FAIL element.value should be ABC0123456789. Was 0123456789.
