Steps to reproduce:
I ran into this issue when developing a website with SemanticUI. A table cell had its class attribute set to "right aligned bottom aligned". The SemanticUI stylesheet contains the following rule:
.ui.table [class*="bottom aligned"]
Can also be reproduced by setting the class attribute to something like "test something test" on any element (for example the body)
Actual results:
When hovering the element, the extra redundant classname was removed from the element, resulting in above CSS rule not working any more.
Expected results:
The class attribute should remain unchanged

Can you provide a minimal example, e.g. via https://jsfiddle.net/?

I created an example: https://jsfiddle.net/jbove1gn/, but it turns out that the culprit was an extension (https://addons.mozilla.org/en-US/firefox/addon/simple-lorem-ipsum/). I figured it out because the fiddle only worked on Firefox Developer Edition (where I had the extension installed) an not on the Standard Firefox. I will file this bug with the developer of the extension.
Sorry for the inconvenience...
