Inserted block 1000 times larger than expected

Hi @jeremy5, (and @wim)
I thought I could use this workaround to edit all the blocks in Model space, but seems not to work when you have text in you block because somehow when you open the file in model space the text has disappeared (Exported block with text loses text - Rhino / Rhino for Windows - McNeel Forum).
Any idea why?

@wim

Is this expected? This is a really strange behaviour in my oppinion.
