Previous button not working after clicking on today button in month view

[jaspervhaastert]

Hi!

The previous button doesn't work anymore after the today button has been clicked at certain dates.
When you click the next button, the previous button will start to work again.

As mentioned by @haksolo, it seems it has something to do with the current date.
I've tested it again and it happens only when the date is between 2019-03-29 and 2019-03-31 (inclusive).

Steps to reproduce

1. Click on the previous or next button (this will work fine).
2. Click on the today button.
3. Click on the previous button (this is where it won't work).
4. Click on the next button.
5. Click on the previous button (this is where it will work again).

Let me know if you have any questions!

I believe it has something to do with today's date 2019-03-31, a bug actually. Try again testing it by tomorrow.
