Wooden button output a redstone signal longer then normal. Stone buttons are unaffected.

What I expected to happen was...:
To use wooden button in my redstone build alongside stone ones and for them to give the same signal length.

What actually happened was...:
While hitting the stone one, it worked but the wooden one didn't. After more research it was found that the wooden buttons now give out a redstone signal longer.

Steps to Reproduce:
1. Put down a stone and wooden button

2. Press one and time it

3. Repeat with other button

The time difference should be quite noticeable and if done in a less precise way should still show the same results.
