Datepicker - inconsistency on input (fractional) height - position fixed issue

[Florian Lacreuse]

Hi,

To determine the top value for a position fixed datepicker, the input height is needed but 2 different methods (in 2 different places).

1. ​https://github.com/jquery/jquery-ui/blob/master/ui/widgets/datepicker.js#L778 => use of offsetHeight, so we always get an integer (33px for instance).

2. ​https://github.com/jquery/jquery-ui/blob/master/ui/widgets/datepicker.js#L880 => use of outerHeight(), so we may get a fractional number (33.5px for instance).

Result : the check line 886 (​https://github.com/jquery/jquery-ui/blob/master/ui/widgets/datepicker.js#L886) may be false in some case and thus the scroll height is not taken into account. The datepicker position is wrong in these cases.

JQuery method outerHeight() should be used in both case. What do you think?

Kind regards.
