If you're using Google IME, the IME is located in the lower left corner of the window. (MS-IME was the correct placement)
I also tried with Beta14 and the Google IME was positioned correctly. In other words, it's a bug that's happening in Beta15.
The same applies to input fields such as search boxes.

### Steps to reproduce

The situation is the same for all places where characters can be entered.

### Minimal reproduction project

It doesn't depend on the project and happens when using Google IME in the beta 15 editor.
for (int i = 0; i < key_event_pos; i++) {
		KeyEvent &ke = key_event_buffer[i];
		switch (ke.uMsg) {
			case WM_CHAR: {
				
				if (!KeyMappingWindows::is_extended_key(ke.wParam) && ((i == 0 && ke.uMsg == WM_CHAR) || (i > 0 && key_event_buffer[i - 1].uMsg == WM_CHAR))) {
					static char32_t prev_wc = 0;
					char32_t unicode = ke.wParam;
					if ((unicode & 0xfffffc00) == 0xd800) {
						if (prev_wc != 0) {
							ERR_PRINT("invalid utf16 surrogate input");
						}
						prev_wc = unicode;
						break; 
					} else if ((unicode & 0xfffffc00) == 0xdc00) {
						if (prev_wc == 0) {
							ERR_PRINT("invalid utf16 surrogate input");
							break; 
						}
						unicode = (prev_wc << 10UL) + unicode - ((0xd800 << 10UL) + 0xdc00 - 0x10000);
						prev_wc = 0;
					} else {
						prev_wc = 0;
					}
