Static Text instances result in warnings

[twilson90]

sample fla + swf:
fonts.zip

The flash file above contains 3 text fields with 3 different fonts.

On processing the swf I see this:

src/swf/SWFTimelineContainer.hx:258: WARNING: excess bytes: 2, Tag: DefineFont3, Index: 3
src/swf/SWFTimelineContainer.hx:258: WARNING: excess bytes: 2, Tag: DefineFont3, Index: 7
src/swf/SWFTimelineContainer.hx:258: WARNING: excess bytes: 2, Tag: DefineFont3, Index: 11

If I add a dynamic text field with the same font family as one of the static text fields, then one of the warnings disappears.
