Japanese language input keys/Menu key zoom out graph view

When using a Japanese keyboard, using Japanese language input special key(halfwidth/fullwidth/kanji key) zooms out graph view in BP editor and Material editor. It seems the menu key makes the editor zoon out, too.

On Windows7, the zoom out also happens when enabling GoogleIME and entering Japanese comments to graph view nodes.

Japanese language input keys, especially the halfwidth/fullwidth/kanji key, is used to toggle Japanese input status, and expected to be used often when writing comments in these editors, so this behavior is very annoying.

This happens in 4.18.0 and main. This is a regression from 4.17.

(Japanese keyboard required if you test Japanese input keys)
1. Open Blueprint Editor or Material Editor and show graph view
2. Press Japanese language input special key(e.g. halfwidth/fullwidth/kanji key, alphanumeric key, non-conversion key, conversion key, katakana/hiragana/rōmaji key) or menu key
3. Graph zoom out

Expected result: Pressing these keys does not affect zoom
