What happened?

I tried to use the API selectByIndex and realized that the input event wasn't dispatched in Chrome. I tested both chrome stable and canary versions.

It's not clear to me if this is a bug in webdriver.io or a bug in Chrome BiDi implementation, because webdriver.io implementation is finally just a click: https://github.com/webdriverio/webdriverio/blob/e86efccd84e20b01713a43113d166d8deb397edc/packages/webdriverio/src/commands/element/selectByIndex.ts#L33-L70

My understanding is that the Chrome implementation is in https://source.chromium.org/chromium/chromium/src/+/main:chrome/test/chromedriver/element_commands.cc;l=285-297, and ultimately to this minified JS, but it's difficult for me to go beyond that.

What is your expected behavior?

The input event should be triggered and dispatched.

How to reproduce the bug.

1. Clone the project https://github.com/julienw/webdriver-select-by-index-bug
2. Run npm install
3. Run npm test

=> notice this fails in chrome but not in Firefox
