### Godot version

4.0beta14

### System information

windows 10, gles 3, nvidia graphics

### Issue description

on beta 14, you cannot drag anymore a node from the scene tree to the script editor to get the node path or the ```@onready``` var snippet

### Steps to reproduce

Using beta 14, try to drag a node from the tree inside the script editor and see the arrow cursor turn into a circular white and red stop sign icon.

Note that this happens even if the script belongs to the currently opened scene.

### Minimal reproduction project

N/A
ScriptLanguage::LookupResult result;
			if (script->get_language()->lookup_code(tx->get_text_for_symbol_lookup(), word_at_pos, script->get_path(), base, result) == OK) {
				open_docs = true;
			}
		}
		if (has_color) {
			String line = tx->get_line(row);
			color_position.x = row;
			color_position.y = col;
			int begin = 0;
			int end = 0;
			bool valid = false;
			for (int i = col; i < line.length(); i++) {
				if (line[i] == '(') {
					begin = i;
					continue;
				} else if (line[i] == ')') {
					end = i + 1;
					valid = true;
					break;
				}
			}
			if (valid) {
				color_args = line.substr(begin, end - begin);
				String stripped = color_args.replace(" ", "").replace("(", "").replace(")", "");
				PackedFloat64Array color = stripped.split_floats(",");
				if (color.size() > 2) {
					float alpha = color.size() > 3 ? color[3] : 1.0f;
					color_picker->set_pick_color(Color(color[0], color[1], color[2], alpha));
				}
