bug(web): macOS-Chrome chiral key behavior #6876

Open jahorton opened 2 years ago

jahorton commented 2 years ago

This bug was discovered during testing of #6808 with the "Development Chirality Test Keyboard" found at web/testing/chirality.

Test Results

All tests done on iPad mini 6 running iOS 15.5.

Type keys ertyu while holding LAlt on the hardware keyboard, output ´®ʈɥ¨ instead of the expected ɛɽʈɥʊ. See the comparison below.

With Keys actual output screenshot of actual output expected output
OSK LAlt + ertyu ɛɽʈɥʊ ɛɽʈɥʊ
Hardware LAlt + ertyu ´®ʈɥ¨ ɛɽʈɥʊ

In Chrome on Windows 10 Pro 21H2, the keycaps shown do correspond with keys triggered and fired on the hardware keyboard.

Failed this test for now as it doesn't work on macOS.

Interestingly, the issue doesn't reproduce if you use Chrome on macOS to simulate an iPad; you need to be testing against macOS itself, not Android or iOS.

Note that there is an outstanding design issue around Alt/Option and Ctrl on macOS, not limited to web platform. See #734, #875, #5721.
