### System information

win11，core i7 13700,  GTX4090

### Issue description

Just look at this gif.

It seems that it was block by Static Type Checking.

If it's right.

Why it doesn't just disable other option except for String and StringName?

### Steps to reproduce

1. first select string type
2. input a text
3. change type
4. change back to string  -- it don't work
5. change to stringname -- it works
6. change back to string -- it works

### Minimal reproduction project

I think it don't need reproduction project.
const int max_sc_width = String::num(max_sc).length() * max_digit_width;
			while (!step_found) {
				int min = max_sc_width;
				if (decimals > 0) {
					min += period_width + max_digit_width * decimals;
				}
				static const int _multp[3] = { 1, 2, 5 };
				for (int i = 0; i < 3; i++) {
					step = (_multp[i] * dec);
					if (step * scale / SC_ADJ > min) {
						step_found = true;
						break;
					}
				}
				if (step_found) {
					break;
				}
				dec *= 10;
				decimals--;
				if (decimals < 0) {
					decimals = 0;
				}
			}
			if (use_fps) {
				float step_size = animation->get_step();
				if (step_size > 0) {
					int prev_frame_ofs = -10000000;
					for (int i = 0; i < zoomw; i++) {
						float pos = get_value() + double(i) / scale;
						float prev = get_value() + (double(i) - 1.0) / scale;
