TEST_ANDROID_5: Using an Android 5.0 (Lollipop) device with its originally-installed version of Chrome...

1. Install and launch the Keyman app for Android
2. Verify that no errors happen on startup
3. Swap to sil_euro_latin for English if it is not already the active keyboard/language combination.
4. Type app.
5. Verify that the predictive-text banner is visible and shows reasonable suggestions.

This may be easiest to do through Android Studio emulation.

Test specification and instructions

• ✅ TEST_ANDROID_5 (PASSED): Tested with the attached PR build (Keyman 17.0.152-alpha-test-9409) in Android 5.1 Lollipop OS / API 22 Simulator and here is my observation: 1. I did not see the keyboard error message after opening the Keyman In-App. 2. Installed another keyboard using Settings option and I noticed that there is no keyboard error message after the new installation. 3. Typing 'app' in the text input screen shows the suggestion words fully visible on the banner. Seems to be fixed and working fine. Thanks. (notes)

Is this the only minify that needed to specify the es5 target?

Is this the only minify that needed to specify the es5 target?

The standard esbuild config setting already includes it; this lm-worker specific one doesn't reference that default, though.
