Except they already do, every day in multiple applications such as:

Spotify

Microsoft Office

NetFlix

Chrome

FireFox

...the list goes on. There is no such thing as a standard UI or behaviour at this point.

Any one that owns a mobile device already has to be used to a mixture of UIs every time they switch between devices or specific applications.

I couldn't actually read the entire article on iOS because of the weird scrolling on a large block of code that more than filled the entire screen.

Using the reader mode resolved the problem for me.

That's interesting. Are you on an iPhone? Reader mode is not enabled on that page for me.

Yes, and the reader mode was not available to me a first too. I believe I used the option to request the desktop page and then the icon appeared in the url bar.

Behavior I can understand, but there is nothing difficult to "put up with" about the look of gtk or qt in Windows.
