Back and forward buttons on a keyboard do nothing

Expected outcome

Back and forward buttons on a keyboard should behave exactly like back and forward buttons on a mouse.

It behaves correctly in Nemo since at least version 5.2.4 in the very same Mint Xfce 20.3, let alone the newest Nemo version of 6.2.1 in Mint Cinnamon 22(.0) beta.
