Short description of error
Unable to set the Start Frame to a negative value, even after enabling it through the configuration

Exact steps for others to reproduce the error

In the Animation tab, enable "Allow negative frames" and close the configuration
In the Start frame dialog, try to put any negative number, it will just put a cero value

The Preview Range is allowed to go into negative range, however the rendering range is not (some rendering formats dont allow for negative frames).

These are two different things, toggled by the "Clock" button:

It is a bit of a convoluted workflow, but working as intended atm.
Hope this makes sense? Will close for now (but feel free to comment again if issues persist)

Note: this was even made stricter recently (it was still possible to set the rendering range to negative values using certain operators), see ca38bce46a
See also #81534 ("Allow negative frames" does not allow entering negative start-/end frame)

I was talking about that same Preview Range, it doesn't work for me. What could be wrong?

The Clock button is pushed (blue)?
