Prevent or Override Text Copy Popup after Touch Press

Question

I'm trying to prevent the default popup (which includes Copy, etc.) from appearing when touch pressing on text in Chrome and other browsers. Specifically I want to replace this popup with my own commands. I still want the text to be selectable via mouse and touch. In other words:

I can't seem to find any solution that would not completely disable text selection and/or other pointer input.

Handling contextmenu with preventDefault at the window and span level do not work, nor does handling touchend.

Thanks for any suggestions!

Edit: It looks like overriding oncontextmenu works on Mobile Chrome but not Windows Chrome. Other people report this not working on iOS. Is there any general purpose solution that works on all browsers? Thanks!
