Media Query not firing when narrowing down if document width equals to the largest breakpoint

Media Query not firing when narrowing down if document width equals to the largest breakpoint.

Sandbox: https://codesandbox.io/s/oqvyx99o4z

**Solution:**
I've checked previous commits and saw a [commit](https://github.com/akiran/react-slick/commit/e1611c2f6f9ad0256d160c01e89493648f8537f4#diff-e8eaa42a1b8ab4981d9272be425c03df) related to this issue.
Same change must be applied to the full screen media query by incrementing minWidth value by 1.


If current width is equal to largest breakpoint, narrowing down the page up to closest breakpoint does not update slide numbers.

**Expected Behavior**
After narrowing down up to closest breakpoint, there must be 3 slides

**Current Behavior**
It shows 4 in this example:

**Steps to Reproduce**
- Go to this sandbox: https://codesandbox.io/s/oqvyx99o4z
- Resize the window to 1024px, which is the value of largest breakpoint.
- Narrow down the window to a value bigger than the closest breakpoint value. (This is example, it is 600px)

**Context**
- react-slick: 0.23.2,
- react-dom: 16.5.2,
- react: 16.5.2
- Google Chrome: 71.0
- MAC OS X: 10.13.6
