Description
I'm using mri@1.2.0.
const headerAliased = {alias: {H: 'header'}}
mri(['-H', 'one', '--header=two'])
// as expected: { _: [], H: 'one', header: 'two' }
mri(['-H', 'one', '--header', 'two'])
// as expected: { _: [], H: 'one', header: 'two' }
mri(['-H', 'one', '-H', 'two'], headerAliased)
// as expected: { _: [], H: [ 'one', 'two' ], header: [ 'one', 'two' ] }
mri(['--header', 'one', '--header', 'two'], headerAliased)
// as expected: { _: [], header: [ 'one', 'two' ], H: [ 'one', 'two' ] }
mri(['-H', 'one', '--header=two'], headerAliased)
// not expected: { _: [], H: 'one', header: 'one' }
mri(['-H', 'one', '--header', 'two'], headerAliased)
// not expected: { _: [], H: 'one', header: 'one' }

Research direction
Reproduce the issue with the four mri argument arrays shown in the report, comparing repeated aliases with mixed short and long forms. Trace the argument-parsing entry point and verify that mixed forms preserve both values under H and header, matching the repeated-form results.
