[yew-devel] [PATCH yew-widget-toolkit] widget: dropdown: update picker placement after showing

[Dominik Csapak]

It seems that under certain circumstances (e.g. a dropdown in a dialog)
updating the position of the picker before it's openend (it's a
popover) does not work properly in safari/webkit/epiphany.

To fix this, update the picker placement after opening it. What exactly
is the cause (e.g. if it's a browser bug or our css/aligning) is yet to
be determined.

This fixes an issue on webkit (tested with epiphany) that opening
dropdowns in a dialog did not show the dropdown properly.
