Floating menu - remove composition check

[dkrym]

I did some more debugging on #1994 and found out that the problem (floating menu does not hide when you type) happens when composition is true (https://firefox-source-docs.mozilla.org/editor/IMEHandlingGuide.html).

The common cases I found:

• Japanese keyboard on both IOS and Android (Floating menu mobile chrome #1994 (comment))
• Typing on Android before you insert space as it uses autocomplete and autocorrect (Floating menu mobile chrome #1994 (comment))
• Interestingly, I have autocomplete and autocorrect on IOS and it does not go to composition

This PR simply removes check if composition is true. I use floating menu for both menu on empty line (as Tiptap example does) and menu attached at the end of the current line as you type. In both cases, I want update position/hide menu on typing any character, even if it is in composition mode.

I think we don't care for composition and shouldShow() should handle it.

The question I have is Was check for composition added for any specific reason?

I don't have experience with composition so maybe I am missing something and the check is actually needed, in that case reject this PR please.

Fixes #1994

Thanks! Great finding. I don’t think we need the composition check here 👍
