Hm, looking at my settings, I also have the map set on the first 'Large and medium size' layout option. I also have the width set to 'Stretch' under the Style settings for the map. (My map widget is also contained within a Section widget, which has 'Stretch' set for its width, too, but that won't apply for everyone.) Maybe check the width settings on your map? If you have a defined width in pixels or a percentage buffer for the position, I could see that messing it up, maybe. Here is a link to one of our apps where you should be able to see the Home and Zoom buttons moving left and right when you open/close the sidebar.
I did also notice that if the app is open on a narrow(ish) screen like a vertical tablet, the Home/Zoom buttons will stop dynamically moving with the sidebar and will let it cover them. But in your screenshot doesn't look like that would be the problem.
