Fwd: [BUG] Sparse tree does not work on properties with dashes

[Fabian Kurmann]

Dear maintainers,

EXPLANATION HERE

I can reproduce it with the sample in the annex, following the steps
below:

- Start Emacs with 'emacs -Q'
- Open a new Org file
- Add the contents of the Annex
- Type 'C-c /' and then 'p' for property.
- Select "TEST-HELLO"
- Select any of the two values

Expected behaviour: produce a sparse tree.

Actual result: no sparse tree.

Best, Fabian
