Clicking on the Favorites button while the search field isn't empty shows Applications page

1. Start typing something
2. Click on "Favorites"

Should be: you see the Favorites page.
What happens instead: you still see the Applications page, only with "All" category shown and the search field cleared.

LMDE, mintMenu 5.4.9.

Note: happens only when "Remember the last category of search" is turned off.
