Update dynamic height adjusting

The current dynamic height adjusting workaround might cause that a
flicker problem happens in the collapsing toolbar and it might cause
that the collapsing toolbar has different background colors in some
setting pages. The new Material library has already supported the
dynamic height adjusting for multi-line titles, so we will use the new
mechanism instead.

Test: visual verified
1) Navigate to permission pages
2) Observe the title and check if it has different background color and
is overlapping with the back arrow
