`Document.execCommand()` may cause firing DOM events and/or running some
observers. Therefore, web apps can call it recursively. However,
Chromium has already stopped supporting it (since 2014).
And it'll be documented in execCommand spec.
This is testing in Nightly and early Beta since 75 (Feb, 2020). So,
I'd like to drop the support in Release channel and late Beta too
starting from 82, but it's still under COVID-19 situation so that if you
have some concern, let me know.
