[Bug 53157] Re: Terminal resizes when changing tab

[Mika Fischer]

Interestingly the amount of the enlargement depends upon the amount of
resizing done beforehand.

Every tab switch adds the amount of rows and columns that the window has
more than the default (80x24 for me).

So if you resize to 81x25 every tab switch enlarges the window by one
row and one column...
