Can't change left and right margins after selecting "Custom" page size
Create a new score, go to Layout > Page Settings... and select Custom as page size.
Change width and height. For example, put 100.00mm and 100.00mm.
Note that the left and right odd page margins are 1.00mm. Try to increase them.
Result: we can't. The workaround is to close the Page Settings dialog and open it again.
Config: MuseScore 7ab8acd on Xubuntu 14.10.

Likely related to #35616: Page Settings: the option "Custom" is displayed as "A4". The code seems to assume "Custom" is first in the list of sizes, but it's actually last, and this confusion has numerous side effects. This is probably one of them.
I don't think it's related. Default width and height for "Custom" is 1.00mm (by the way, it may be changed for something more "realistic", for example 100.00mm). The left margin is set to 1.00mm (it can't be wider than the page size). So does the right margin.
When we increase the page size, for example 200.00mm x 250.00mm, the margin fields don't "see" the new size, and prevent the user to increase more than the previous page size 1.00mm.
Right you are, not really related. But I fixed them together, and also made it so selecting Custom as page size doesn't actually change the current size at all:
