I cannot test myself but I saw you were using an outdated version of Vue 1. Please test with the updated version

Hi @gaecom . I found this behavior is IME specific. That is, Chinese IME will not input any characters without confirmation. The same behavior can be produced on plain input and various websites, e.g. GitHub.
If you change another IME like Japanese IME, it will work as expected.

I wonder it can be fixed in JS library.

FYI ignoring composition events on desktop is necessary to ensure correct syncing behavior. Not sure if this is even possible to fix if the user does not finish composition.

@HerringtonDarkholme Do you think we can close this?

@posva Yes I think so.

If some one has come up with a new solution, we can open a new issue. For now I don't think there is a panacea.
