Export enters an endless loop when called from within a live editor file #375

For example,

[x,y] = meshgrid(1:15,1:15);
z = peaks(15);
T = delaunay(x,y);
p = trisurf(T,x,y,z);
export_fig(p.Parent, "test.png");

does work as intended when used from within the command window or a regular matlab file, but it seems to enter an endless loop when used from within the live editor (a *.mlx file). The issue seems to be related to drawnow.

A possible workaround is to undock the figure before exporting. This does however prevent it from being shown in the output column of the live editor:

[x,y] = meshgrid(1:15,1:15);
z = peaks(15);
T = delaunay(x,y);
p = trisurf(T,x,y,z);
set(p.Parent.Parent, 'Visible', 'on');
export_fig(p.Parent, "test.png");
set(p.Parent.Parent, 'Visible', 'off');

Matlab version: 2022b
