Will fire `beforeinput` event when user uses build-in autocomplete etc. 2. Set its `inputType` to `insertReplacementText` as defined by the spec. 3. But make it not cancelable for protecting Firefox users from web apps which unexpectedly blocks default actions of `insertReplacementText`. https://phabricator.services.mozilla.com/D93206 2033392 3 mike 2024-05-05 22:12:40 -0700 Nakano-san, Do you know if we have any relevant WPT tests for this? 2033393 4 mike 2024-05-05 22:14:54 -0700 Nakano-san, Is the Chrome behavior for this case spec-conforming? 2033645 5 masayuki 2024-05-07 00:30:26 -0700 (In reply to sideshowbarker from comment #3) > Nakano-san, Do you know if we have any relevant WPT tests for this? Unfortunately, there is no WPTs because the test driver does not provide a way to work with browsers' UI like a popup of autocomplete. (In reply to sideshowbarker from comment #4) > Nakano-san, Is the Chrome behavior for this case spec-conforming? No, I filed Chromium bug too. https://issues.chromium.org/issues/40673974
