EditRowPlugin not rendering date fields correctly

I have a table with a date field in it. Included below is a small sample of it for demonstration.

Note:

Others on the IRC channel have verified that this problem also exists with the current version
I have my EditRowPlugin to process %EDITROW%, so I can control when EditRowPlugin is being used and when EditTablePlugin is being used.

The EditTable example source looks like this:

%TABLE{id="showstabledate" sort="on" initsort="1" initdirection="down" tableborder="2" tablewidth="100%" columnwidths="1&,10%,10%,10%,60%" headerrows="1" footerrows="0" headerbg="#ddddff" headeralign="left"} %EDITTABLE{format="|date,10,,$percntY$percntm$percntd|text,6,|text,6,|text,40,|" changerows="on" headerrows="1"}%
| Date | Time | Channel | Show |
| 20120522 | | SyFy | Face Off |
| 20120525 | | foo | bar |

When I edit that table and enter the date field, I correctly get the calendar. When I save it, the date is correctly displayed in YYMMDD format.

The EditRow example source looks like this:

%TABLE{id="showsrowdate" sort="on" initsort="1" initdirection="down" tableborder="2" tablewidth="100%" columnwidths="1&,10%,10%,10%,60%" headerrows="1" footerrows="0" headerbg="#ddddff" headeralign="left"}% %EDITROW{format="|date,10,,$percntY$percntm$percntd|text,6,|text,6,|text,40,|" changerows="on" headerrows="1"}%
| Date | Time | Channel | Show |
| 20120516 | | SyFy | Face Off |
| 20120530 | | Foo | Bar |

When I edit that table and enter the date field, I correctly get the calendar, and when I click on a date it shows it in YYMMDD format. However, when I save the table, the date does not display in YYMMDD format, and a bunch of source code (TML? JavaScript?) is shown instead of the value. It looks like this:
