css bug for buttons in iframe form

see attached jpg for visual.
right side of image… grid
left side of image… iframe containing the edit form.
the editable form contains two buttons that were created as links.

Assumption: form buttons (grid -> toolbar) inherits css formating from the grid.

Problem: form buttons (form settings -> buttons) do not comply with any (form or grid) CSS rules when form that contains added buttons is placed inside of grid iframe.

Please fix.
