Pressing TAB after getting search results reveals a hidden Skip to content button that jumps to the first link with tab. This button doesn't appear when selecting TAB after having searched with a lens.
To replicate:
Search normally, press tab immediately after results load.
Search the same query with a lens, press tab immediately after results load.
The second time will not show the Skip to content button like the first.
^ This image shows the hidden button.

^ This image does not.
I expected the Skip to content button to appear like it does with regular searches.
