Among other goals, the new fontification is aiming to avoid such bad
surprises.
As for lang parameter support in example blocks, would you mind creating
a separate feature request thread? Extending export blocks export will
require changing in parser syntax and thus should be discussed carefully
in a separate thread.

Can you (and other interested users) try the following value of
org-script-display and let me know if it looks acceptable:
(defconst org-script-display '(;; The values are tweaked to not change
;; the line height.
((raise -0.1) (height 0.7))
((raise 0.25) (height 0.7))
;; Alternative properties for tables.
;; FIXME: We cannot change the text
;; height because it will alter the

;; org table are aligned via pixel
;; width).
((raise -0.5))
((raise 0.5)))
"Display properties for showing superscripts and subscripts.")

Thanks! Now it is crystal clear what was the reason behind the different
fontification inside/outside the tables. I will add the explanation to
comments.
Best,
