`document.execCommand("removeformat")` removes any elements in the range which
are editable, not `<a>`, not block and a container.
https://searchfox.org/mozilla-central/rev/dd7e27f4a805e4115d0dbee70e1220b23b23c567/editor/libeditor/HTMLStyleEditor.cpp#760-763
This means that it removes hidden elements like `<script>` and `<style>`,
or non-HTML elements like SVG elements. However, the unofficial document
of `execCommand()` lists up elements which should be handled by the command.
https://w3c.github.io/editing/execCommand.html#removeformat-candidate
Additionally, Chrome respects this list since not including `<del>` element
into the list does not make sense but Chrome ignores it. So, we should
respect the list.
