Set parameter bounds for improper integral

∫x²dx +5 ie, ∫(x^2,x)+5

they enter

∫x²dx+5 ie, ∫(x^2,x+5)

The error is very subtle visually in Textbook mode. You'd only notice it if you knew to look for it.

Both had "∫x²dx+5" in CAS input history ... not just subtle, but identical

Since CAS does not support ∫x² d(x+5) = x³/3 + C, why should the space be necessary ?
Both should have parsed as ∫(x^2,x) + 5
