The property 'extra-offset is applied at a late stage, when the positions
of layout objects have already been determined. Here, the staves have been
moved apart to accommodate the tall markup. Setting 'extra-offset moves
your bracket, but no recalculation of spacing happens.

The problem is that TextScript is an outside-staff-object, and the spacing
between staves will be calculated so that there are no collisions when it
is placed above the staff.
Below, I've set 'outside-staff-priority to #f, meaning that the grob will
be treated as a within-staff object. You can then move it around with
'extra-offset. I used 'X-offset and 'Y-offset so the spacing will
accommodate the object,
\score {
\new PianoStaff <<
\new Staff { \notes }
\new Staff {
r4
\once \override TextScript.outside-staff-priority = ##f
a'2.^\tweak #'Y-offset #-1 ^\tweak #'X-offset #-1 \bracket }

}
HTH,
