#35789: Theme screenshots flicker on initial hover with fresh cache in Firefox.

With a freshly cleared cache, theme screenshot images appear to
jump/flicker/flash on the initial hover. This behavior is not intended and
can be easily solved by using the `will-change` property to force hardware
acceleration which fixes the initial paint. See:
https://developer.mozilla.org/en-US/docs/Web/CSS/will-change
Due to how fast the flicker is, you will only see '''twentyfifteen''' and
'''twentyfourteen''' theme screenshots flicker in the following screencast
although all 6 screenshots flickered initially.

Steps to reproduce:
1. Open latest Firefox
2. Go to src.wordpress-develop.dev/wp-admin/themes.php
3. Refresh the page and bypass the browser's cache. (Mac `cmd` + `shift` +
`R`)
4. Hover theme screenshots.
