Pink vertical line on every page in landscape mode

[Tropix222]

To reproduce (the order doesnt matter):

1. Create new page
2. Put the device in landscape mode

Extra info:
When not in landscape mode it doesn't appear. It is around (1738, y) coordinates (exactly where the showed pagination line ends.). and it goes down to almost 3 subpage length.

If exported as PDF with pagination, it appears on every page. Without pagination it only appears for ~3 subpage length, then it disappears. (I added the two produced PDFs)
not_paginated.pdf
paginated.pdf

If exported as PNG or JPEG the line only goes down to 1 subpage length.

However the line is always visible in the app, even after the 3 subpage length (that's why the PDFs are this long, because I didn't know where to stop).

(Honestly I love this app and very grateful that all of you guys are working on it, it carried this whole semester.)
(Edits: This is my first github issue idk what I'm doing)

The magenta line was intended to indicate the margin -- what won’t be exported.

Screens aren’t exactly A4 proportions, so the app should take the shortest edge of the screen as the reference for scaling. In landscape mode the app does not scale the writing, so to indicate what won’t be visible in vertical orientation I added this line. The export was intended not to include what’s in the margins.

So the problem is that the app exported the margins when it wasn’t supposed to. Basically, the line on export should be exactly at the right edge of the screen, or rather not visible at all.

The current approach to doing this is not perfect; there should be a setting to choose paper size and orientation. For now, the next thing I want to focus on is #171
and investigating crashes, but my time is quite limited right now. So this issue will have to wait.
