This is fine.  But anyway I think in its current state
treesit-sexp-type-regexp is underdesigned as noted in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=62238#59
so no tweaking could fix its design flaws.  For example,

  foo = {
    a: b
  }

when point is on the left curly bracket, 'C-M-f C-M-b' doesn't
move back to the original position, etc.
