[bug] Clicking anywhere on perfect island reward screen can select the wrong award

[MarmaladeMan]

Macbook Pro mid-2014 model
macOS Catalina v10.15.3
Into The Breach version: GOG v. 1.1.22 (11-8-2018)

Repro steps:
- Start a new game
- Complete a perfect island
- At the perfect island reward screen, hover over some reward to inspect its attributes
- Move cursor elsewhere on the screen (note: for me, the on-hover info did not disappear when I moved my cursor)
- Click somewhere, either on the reward screen modal, or off the reward screen modal (both seemed to trigger the behaviour for me)

Expected result:
- Perfect island reward screen should not disappear until a reward has been selected. Or, the option to select the reward before leaving the island should be available.

Actual result:
- The reward which you previously hovered over is selected.
