Is there an error in the subplot function in 2025a version

The following lines were added to the subplot function in version 2025a (line 291):

if ancestorFigure.Units == "normalized"

waitfor(ancestorFigure,'FigureViewReady',true);

end

That code isn't in version 2024a.

Because of this, I'm experiencing issues that cause the code to stop running when using subplot in this way:

t = 0:0.1:10; y = sin(t);
figure('Units','normalized','Position',[0 0 0.3 0.3])
subplot(1,2,1)
plot(t,y)
subplot(1,2,2)
plot(y,t)

●

I deleted those lines and everything works fine.

Has anyone else encountered this error?

Does anyone understand the need for those lines of code?

Works for me in R2025a for Intel Mac in regular .m files.

However it appears to hang when the code is in a mlx (LiveScript) file.

Yes, my problem is with a MLX file.

It doesn't happen with tiledlayout(). I guess they assume everyone has transitioned to that.

t = 0:0.1:10; y = sin(t);
figure('Units','normalized','Position',[0 0 0.3 0.3])

tiledlayout(1,2)
nexttile; plot(t,y)
nexttile; plot(y,t)

This behavior is not intentional. I'd suggest reporting this here:
