### System information

Windows 11 22H2

### Issue description

There's not much to it, simply noticed that if you have Find or Find+Replace opened in the Script Editor, the Multi-Caret functionality seems to stop working -- forcibly removing all other carets after the first character is typed. I'd expect the Multi-Caret to remain until unselected by clicking elsewhere.

The content of what's in "Find" doesn't matter, it happens regardless.

### Steps to reproduce

1. Open the Find or Find+Replace tool in the Script Editor _(nothing has to be inputted)_
2. Add multiple mouse cursors with Ctrl+Alt+Click **OR** highlight something and then highlight additional duplicates with Ctrl+D _(or synonymous keyboard shortcuts depending on OS)_.
3. Start typing as if going to add or replace in all locations where the multi-caret is

### Minimal reproduction project

N/A
text_editor->begin_complex_operation();
	Vector<int> caret_edit_order = text_editor->get_caret_index_edit_order();
	for (const int &c : caret_edit_order) {
		const int cursor_column = text_editor->get_caret_column(c);
		int from_line = text_editor->get_caret_line(c);
		int to_line = text_editor->get_caret_line(c);
		int from_column = 0;
		int to_column = 0;
		int cursor_new_line = to_line + 1;
		int cursor_new_column = text_editor->get_caret_column(c);
		String new_text = "\n" + text_editor->get_line(from_line);
