Outer frame not resized correctly in DevDocs ZIMs #685
Description
This issue affects Kiwix JS and Kiwix PWA, but not Kiwix Desktop, so it has something to do with the code that resizes the iframe content to fit the window in both apps. When fixed here, we need to backport to Kiwix JS.
The effect is minor, but it causes the app's scrollaway UI to appear and disappear in a slightly disordered manner when scrolling longer pages.
