> `nsIDOMWindowUtils.getLastOverWindowMouseLocationInCSSPixels` records real mouse event only, so we cannot use it on parent process even if Android.  Child process can receive converted mouse event from touch event, it works well on child process only.

Makoto: do you mean `nsIDOMWindowUtils.getLastOverWindowMouseLocationInCSSPixels` provides no touch position if called from the parent process, but it does provide a touch position if called from the child process? If so, I don't understand why [manual test on Ubuntu 22](https://bugzilla.mozilla.org/show_bug.cgi?id=1776843#c4) worked.
