This question already has an answer here:
I've just looked at this answer with the StackExchange Android App. It looks like this:
When you look at "Original Solution", you can see a code block that has a very long line. Currently, there is no possibility to read this line. When I click on this block, it pops up, but I still can't read the whole line.
I think there should be horizontal scroll bars when the content can't be displayed. Or at least I should be able to "drag" the text so that I can read the rest.
