[ilyakonrad]

Describe the bug The last example in the documentation of mdc-select works incorrectly.

To Reproduce Steps to reproduce the behavior:

1. Go to the docs.
2. Scroll down to the last example.
3. Click on RESET.
4. Mark select as touched by clicking on it and then clicking somewhere else so that it gets closed.
5. It is not marked as touched at the bottom until you touch it again.
6. Also, the RESET button doesn't work after the first touch, but works after the field gets proper 'touched' status.

Expected behavior It should probably become touched right after the first interaction.
