[BUG]The preview image doesn't disappear

[flxuan]

Describe the bug

Often, when I hover over the dock icon and the corresponding preview appears, the preview doesn't disappear. Even though the mouse has moved to other areas and has been active there for a long time, the preview still doesn't disappear.

Steps to reproduce

1. Quickly swipe the mouse over the dock application icon
2. At this point, each application icon will display its corresponding preview image
3. Draw the mouse over the dock icon and preview image, and move to other areas for activity
4. It is highly likely that the preview image will still be displayed and not disappear
5. The preview image will only disappear when the mouse hovers over the application icon corresponding to the preview image in the program dock

Expected behavior

When the mouse is not on the dock application icon, the thumbnail disappears

Actual behavior

After the thumbnail is displayed, it often does not disappear
