Research direction

Start by inspecting the formatter source around line 331 and reproduce the reported snippet with a split if condition and trailing comment. Trace how indentation is calculated for the then block, then add or update coverage for this case and verify that the formatted output indents prd correctly.

Written by the indexing model from the issue text.

Description

Comments at the end of this if makes the then block to not get indented.

                            if (prd.source()
                                .isPresent()) // exclude generated productions like casts
                            prd = null;

Line 331. IntelliJ reports this as well.
I think the problem comes from the if condition that got split into two lines. If I move the comment to a separate line, then indentation works as expected.
