All of the following `INPUT` fields have a `size` of 14:

1) Browser default font:

2) Times New Roman (default in M7 Apprunner/Windows) or other serif font:

3) MS Sans Serif (default in IE4.x/Windows) or other sans-serif font:

4) Arial or other sans-serif font:

5) Monospace font (default in Navigator 4.x):

Since the `INPUT` field in test 5 is using monospace font, it should fit exactly 14 characters (eg. the visible string should be "12345678901234", no more, no less).

However, when an `INPUT` field uses a proportional font - as tests 2-4 do - the specified number of visible characters is always an average, not an accurate value. Try filling the field with lowercase 'l' letters or uppercase 'W':s to get the point.
