Content width is exceeding the rounded rectangle x axis

Issue description:

I'm using latest termshot to generate an image based on an ls cmd. I can see that the stdout of my cmd is not fitting into the rounded rectangle but it actually exceeds it(in other words, the list of files and directories is incomplete in the generated image). I unfortunately was not able to understand why, any ideas?

Would be good if you can reproduce this from your side.
