Plot with left and right Y-axes in a mlx fails to export to eps in Live script

Hello, I'm running version 3.44 and I stumbled upon a problem when trying to export a figure with a plot using left & right yyaxis. While trying to come up with a minimal working (failing) example, I have discovered that this problem only seems to happen in Live scripts (`.mlx`). The exported figure is empty and the following warning is emitted:

> Warning: Some uifigure controls cannot be exported by export_fig and will not appear in the generated output .

Same code in `.m` file produces figure normally.
```Matlab
t = linspace(0,10);
x = sin(t);
y = cos(t);

f = figure;

yyaxis left
pleft = plot(t, x, '-');

yyaxis right
pright = plot(t, y, '-');

export_fig(f, 'tryout', '-eps');
```

I'm not very well versed in Matlab, so if you need some more info to replicate this, I'll gladly try to provide.
