New description:
A security bug was removed from the intcomma template filter in Django
4.2.10. But it appears a bug was introduced that misformats numbers when
the intcomma filter is combined with floatformat.
The problem is a leading comma is added to some numbers (I suspect it is
numbers with exactly 3 digits).
Example code that worked in 4.2.7 but now misformatting in 4.2.10:
{{total_amount|floatformat:"2"|intcomma}}
In the attached screenshots the bug is apparent. They are the same screen
displayed using 4.2.7 and 4.2.10. Note the leading comma before 3 digit
numbers in the one screenshot (that's 4.2.10).
