(bug)The showMatchedFeatures function blocks when used in an .mlx file

The showMatchedFeatures function blocks when used in an .mlx file, preventing subsequent statements from executing!

• R2026a prerelease（'26.1.0.3030274 (R2026a) Prerelease'）
• '26.1.0.3133997 (R2026a) Prerelease Update 3'
• on Windows 10 22H2

For example, the code below hangs on the showMatchedFeatures function when run on the R2026a prerelease desktop version — it stays in a “Running” state and never prints the variable c.

img1 = imread("peppers.png");
img2 = img1;

pts1 = randi(500,30,2);
pts2 = pts1;
showMatchedFeatures(img1, img2, pts1, pts2, "montage");

a = 1;
b = 2;
c =a+b

c = 3

Occasionally the following error occurs:

Warning: An error occurred while drawing the scene: GraphicsView error in command: controlmanagermessage: TypeError: Cannot set properties of undefined (setting 'tabIndex')

I couldn't reproduce this. I can see "c = 3" printed in the MLX file within the editor. It looks the "c = 3" also printed in the screenshot you've shared. I'm not sure why the MLX file stays in a running state though. Is that reproducible with other plotting functions like PLOT?

The other plotting functions don't show any issues for now. I can reproduce the problem with the showMatchedFeatures function — you can see it in the MP4 I recorded.
