Addresses post-merge review comments from recent optimization PRs - in particular, for #11177.

User Testing

TEST_LIGHT_GESTURES: Do some light testing of a few gesture-enabled keyboards and make sure things work as well as they did before. Nothing too rigorous - we'll handle that with regression & platform-acceptance testing.

Test specification and instructions

• ✅ TEST_LIGHT_GESTURES (PASSED): Tested using the KeymanWeb (Test Unminified KeymanWeb) page on an iPhone 13 Mobile (iOS 17.4) device and here is my observation: 1. Conducted testing on gesture-related features with the Classic 10-key and Diacritic 10-key Rota keyboards, as well as Gesture Prototyping tests, all of which performed as expected. 2. Installed Keyman 17.0.309-beta-test-11238 on the iPhone Mobile and launched the application. 3. Installed the diacritic_rota keyboard. 4. Tested the App_10_Key_Diacritics keyboard and confirmed that it functions correctly.

Thank you thank you! This is so much clearer without the extra closures and the comments really help for future maintainers. LVGTM
