 == Reproduction Report
 For the test I used this [https://cloudup.com/iPoOjvOKh3j/f test image at
 1724x2300 pixels] (some example dimensions reported in
 [https://github.com/Automattic/wp-
 calypso/issues/52182#issuecomment-825171633 wp-calypso issue 52182]).

 === Environment
 - Hardware: MacBook Pro Apple M1 Pro, Apple Studio Display (5K)
 - OS: macOS 12.6.1
 - Browser: Safari 16.1 and Mozilla Firefox 107.0, browser windows sized to
 1280x1336 at 100% zoom
 - Server: nginx/1.23.2
 - PHP: 7.4.33
 - WordPress: 6.2-alpha-54642-src
 - Theme: dara v1.2.1

 === Actual Results
 - ✅ When using an image whose resized dimensions have a decimal that can
 result in a rounding error (described in [#ticket]), the crop tool handles
 overlay does not appear.

 === Additional Notes
 - Unable to reproduce in Google Chrome 107.0.5304.110 with window sized to
 1280x1336 and 100% zoom.
