It doesn't require zooming in

Summary: Text in subframes isn't properly selected after zooming in: the sequel → Text in subframes isn't properly selected: the sequel

Does "2. Long press Open" mean "Long press on any word (such as "Open" in step 1) to make the blue caret appearing"?

Yes.

I think the key is the numbered list.

It might not be about subframes either

Component: Panning and Zooming → Selection
Summary: Text in subframes isn't properly selected: the sequel → Text isn't properly selected...

Thanks! I think this is a selection bug, and can be reproduce on desktop browser with
layout.accessiblecaret.enabled=true and layout.accessiblecaret.hide_carets_for_mouse_input=false.

By selecting the word "Open" in step 1 in comment 0, and dragging the right caret toward the auto-generated <li> ::marker "1.", the selection range jumps to somewhere unexpected.

This is likely to be an existing bug before ::marker was introduced.
