[flutter_adaptive_scaffold] Fix breakpoint not being active in certain cases like foldables (flutter#7549)
*Replace this paragraph with a description of what this PR is changing or adding, and why. Consider including before/after screenshots.* As pointed out by the docs on this: > Available width and height are classified separately, so at any point in time, your app has two window size classes�one for width, one for height. Available width is usually more important than available height due to the ubiquity of vertical scrolling, so the width window size class is likely more relevant to your app's UI. *List which issues are fixed by this PR. You must list at least one issue.*
