So, with this page:

data:text/plain,%0D%0A%0D%0A%0D%0A%0D%0A%0D%0A%0D%0AThis%20is%20my%20text%20containing%20file_name.pdf

(Copy and paste n go in a new tab to load it.)

, I double-left-click anywhere on file_name and it should open a new tab?

If so, I can't get that to happen. Opera just shows the search popup with the choice to search or copy or snapshot (all with the AI stuff above it).

Is this happening in regular Opera (Opera One) or Opera GX? What specific version as shown at the URL opera://about? What version of Windows?

Does it happen in a test standalone installation too?
