Bad indentation with subquery inside nested paratheses

The following query:

SELECT
    *
FROM
    some_table
WHERE
    AND (row2 = 'b'
        OR row3 = 'c'
        OR EXISTS (
            SELECT
                1
            FROM
                some_table
            WHERE
                row4 = 'd')
        OR (row4 = 'e'));

Gets formatted by pgFormatter 8d0290b0af21054bdb21ea6d83bf4447a8013bfe as:

SELECT
    *
FROM
    some_table
WHERE
    row1 = 'a'
    AND (row2 = 'b'
        OR row3 = 'c'
        OR EXISTS (
            SELECT
                1
            FROM
                some_table
            WHERE
                row4 = 'd')
            OR (row4 = 'e'));

The final OR (row4 = 'e') gets indented one level further to the right than OR row3 = 'c', even though they are part of the same disjunction.

If the OR EXISTS (SELECT 1 FROM some_table WHERE row4 = 'd') part of the query gets deleted, OR (row4 = 'e') gets moved back one indentation level.

This bug only occurs if the disjunction is inside a parenthesis. If the parenthesis is removed, the indentation works as expected.

Start by formatting the supplied nested-parenthesis query with pgFormatter and compare it with the expected output. Trace how the formatter handles the OR EXISTS subquery and the following OR expression; done means the final OR (row4 = 'e') aligns with the other disjunction terms without the subquery being removed.
