Description

Steps to reproduce:
1. Build and run the attached app.
2. Compare the labels of the components at runtime with the labels specified in the source.

Actual Results:
Some characters are duplicated. The number of times the characters are duplicated appears to be related to the number of times that character has appeared earlier in the source (the top text input only has 1 duplicated character while the bottom button has lots).
When I ran this with a 10.0 player, the characters in question appeared as boxes, but the duplication was still visible. Running under a 10.1 player displays the actual characters instead of boxes so the pattern in the duplication is more clearly visible.

Expected Results:
No duplicated characters.

Workaround (if any):
