Width of Barcode Display

[AndyM48]

I have some more questions concerning the principal screen showing the chosen card and barcode. The screen is very nicely presented in two parts: above is the image of the card, and below is the barcode, in a box which is the same width as the card above.

It happens that I only have two types of barcode to display, EAN 13 (13 characters) and Code 128 (19 characters).

So I wonder:

Why is the longer Code 128 code shown in a space which is narrower than the shorter EAN 13 code?

Why is the long, Code 128, number truncated to 17 characters on the display? If I tap the truncated code it is displayed in full in a new window, but in a smaller typeface. Why is it not displayed in full in the principal screen, in a size to fit the space available?
