The button inserted into the container is trimmed to the left side.

This is not removed by adding indentation. As you can see the indentation from the border of the container is significant, but the button is still cut off to the left.

Start by reproducing the reported button-trimming behavior inside a container using the attached example and compare it with the visible container border and indentation. Trace the container and button layout code to find where the button's left edge is clipped. Done means the button remains fully visible without relying on additional indentation.
