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.
