Minor visual bug: Unknown sequence range marker on last aa does not go all the way to end of gene view

[corneliusroemer]

Noticed a small visual bug: the X marker (and frameshift bar) for the last amino acid in a gene does not extend all the way to the end of the gene - which is unexpected because the last amino acid is the last and there shouldn't be anything afterwards:

Reproduce with this, and go to ORF8 view:
