I'm having a weird response from plot in MATLAB online. Plotting data that have extrema using thick lines has a weird response on my browser. Take the following code:

v = [1, 2, 5, 10, 5, 2, 1]
plot(v, "Linewidth", 5)

The resulting image in the live notebook seems to have variable thickness, and only the line segments at the edges are visible. However, when I open a separate figure window, I can see the intended plot correctly. Here is a screenshot:

I'm using Ubuntu 22.04 with KDE. I tried both firefox and chromium and the weird behaviour is still there. On the standalone matlab application, the correct thickness can be shown, so it seems like this is a MATLAB online issue.

Am I doing something wrong? Are there any settings I need to tweak in order to get the right behaviour?

edited the example to make the issue more apparent.
