STR
1. Hold and Drag to make selection1 on paragraph text
2. Make selection2 in a focusable editor(address bar, textarea on the content page)
 == selection1 becomes greyed out, but still highlighted. ==
3. Click and drag on selection1 to switch selection.
4. Middle click to paste. You will get selection2 despite selection1 being the current highlighted selection

Got more info from :acomminos who works on GTK linux. Seems the correct behavior is not to update the selection in this case. Chrome on linux has the same behavior.

For Bug 1261299, specific for macOS I'll have NotifySelectionChanged called in this case to change the current selection that will be sent to macOS services.
