TextScript padding broken over measure rest?

[Paul Scott]

In 2.11.4 the following code doesn't pad the text over the R1.  It works 
fine otherwise.  It also fails with outside-staff-padding.  I see now 
that 2.11.5 is out.  It also fails with 2.11.5.

Is there any way that someone could post the announcement for each new 
version to address@hidden  Some make it; some don't.

#(use-modules (ice-9 optargs))
#(define* (textPad padding #:optional once?)
 (ly:export   ; this is necessary for using the expression
  ; directly inside a block
  (if once?
   #{ \once \override TextScript #'padding = #$padding #}
   #{ \override TextScript #'padding = #$padding #})))

\relative c'' {
 #(textPad 5 #t)
 R1^\markup{ rest }  %tried w/ both "" and \markup
 #(textPad 5 #t)
 a4^"note" b c d
 #(textPad 2 #t)
 c1^"more text"
}
