[Fixed] Filter inventory on multi-category selection with solo item in category

[JP_Finn]

Filter in inventory on multi-category selection with solo item in category, it drops out and not count on items selected the other categories.

e.g.
When dropping items: d | 'tab' | t(ools) | 'letter for paddle' ( and there're more tools still there, all is good.) 'tab' | v(ehicles) | a or enter to select the sole item; punt. Game drops the punt only as the focus is on vehicles and high lighted items in other categories aren't checked.

I believe it's from streamlining the inventory management and decrease of keyboard jockeying with single item drop not requiring space as confirmation.

This calls for a fix. Let's make it so that if there are some items selected already then the single item selection (punt in your example) doesn't count as single item drop without confirmation. But if the punt would be selected first, as the only item in filtered category, then it counts as single item drop without confirmation. This keeps it both streamlined and fixes the issue.

Fixed - persists in 3.62.
