cannot input negative number (capital loss) in the Capital Gains Summary page

[RustRoc]

After I input a negative value at the box "Realized before June 25, 2024". The page encountered an error saying:

Please enter a dollar value greater than or equal to 0.00 in the format of 9,999.99 or 9999.99.

The Summary of capital gains table above, calculated automatically, is correct, though, with negative numbers shown.
