If I pass "NaN" value to this form it will fail with
decimal.InvalidOperation error.

Comment:
Thanks for the report.
This is a regression in cc3d24d7d577f174937a0744d886c4c7123cfa85.
The #7777 originally added handling of `NaN` and `Inf` in `DecimalField`
(in 692fd7da5e5bfe1533c40f94999ea42f9b986356).
It looked redundant but wasn't because `MaxValueValidator` does not handle
`Decimal('NaN')`.
Here's a minimal diff showing that:
{{{
diff --git a/tests/validators/tests.py b/tests/validators/tests.py
index e39d0e3a1c..42665c6ccb 100644

Results in:

You PR here should (partially?) revert
cc3d24d7d577f174937a0744d886c4c7123cfa85 (see #31806 and
[https://github.com/django/django/pull/13212/ the PR for discussion and
related commits]).
Add `max_value` to the existing `test_enter_a_numer_error()` case:

It looks as if test `test_value_placeholder_with_decimal_field
(forms_tests.tests.test_validators.ValidatorCustomMessageTests)` will need
adjusting.
A release note in 3.2.6.txt will be needed.
Good spot.
