Comment 15 for bug 1788495

@Jeff-

Sure thing. I tested on the Mac and the columns also cannot be resized (see attached image). We can resize the space both columns are provided into the canvas but we can't increase the space of the first column by dragging anywhere.

However, on the mac, the columns are auto-sized to fit the full content correctly (they are not on linux), so this is probably less of an issue there.
