Minor Error in account/overview.php

In general, many other phone numbers will exceed 30 characters… but I noticed upon entering my telephone number in account/overview.php of the admin interface that the number cannot exceed more than 10 characters. But unfortunately my number (without spaces!) includes already 11 characters, if I add the international area code for Germany „+49“, the field needs already to have 13 characters since the first „zero“ of the national area code is erased once international callers use my number. Once I’d try to draw the value for this input field in a more readable format, it would include a minimum of 21 characters as I combine „+49 (0) xxx xx xx xxx“ for my number.
