### Godot version

4.0 beta 15

### System information

Windows 10

### Issue description

It happened with both Google IME and MS-IME, and there was no problem until Beta14.
When typing Japanese characters, it is common to select a character from the suggestion window and then start typing the next character before confirming.
In this case, uncommitted characters are forcibly committed, and input of the next character begins.

### Steps to reproduce

It happened with both Google IME and MS-IME in beta15

### Minimal reproduction project

It is project independent and happens in the editor.

		for (int i = 0; i < gutters.size(); i++) {
			if (!gutters[i].draw) {
				continue;
			}
			if (p_pos.x >= left_margin && p_pos.x < left_margin + gutters[i].width) {
