Handling of quotes when composing with IME in Stride

[PwtKCL]

This problem was observed using Windows with Chinese language (over a French keyboard layout, but that shouldn't matter I think).
The issue would certainly apply to all languages using IME to compose text.
When the IME is composing, and we type a double quote in Stride, the mechanism to auto-generate the matching closing double quote fails (and the key hit doesn't produce anything, actually).

For testing this, it is important to make sure the IME is composing. For example, on Windows with Chinese keyboard enabled, when we type we should be sure that the Chinese characters mode is on, rather than the latin letters mode.
