Details:

Code folding doesn't work right when there are while statements:


a = 1:5;
if true
    a(1:2)+=3;
    a(3:end)-=3;
    b = a;
    for i=1:3
        b+=1;
        while true
            a = 3;
        endwhile  %code fold matched with for
        
        if false
            b=3;
            b = a(end); 
            q = b;
        endif 
        a = 1;
    endfor%code fold matched with top if
    c+3;
endif
a = 1:5;
if true
    a(1:2)+=3;
endif


The wrong sections of code are folded in the case shown. I first mentioned
this in bug #51321, and although that bug was fixed, this issue persists. This
bug is also in the dev version.
