Text() causes run of @interact_manual decorated function on focus change ; but Textarea() does not

[BenGardiner]

Description

Text() causes run of @interact_manual decorated function on focus change ; but Textarea() does not

Reproduce

@interact_manual
def doitdoitnow(arg=Textarea('arg')):
  print('u ran me')

when you change focus from the Textarea the function will not be invoked

@interact_manual
def doitdoitnow(arg=Text('arg')):
  print('u ran me')

when you change focus from the Text the function will be invoked

because Text() is the default for any string arguments it is also the case that any string arguments in a @interact_manual decorated function will get run when focus changes away from the automatically generated widget.

Expected behavior

For all functions decorated with @interact_manual the behaviour should be to ONLY execute the function when the button is pushed.
