Can’t select text in draggable options fields for multiselect, radio, checkbox

I’m using FF on a MAC and found that I was unable to directly drag-select text or place my cursor in an option field under the settings for a mutliselect, radio, or checkbox input field. Yet, I was able to select text in the label fields.

I tried manipulating the css and checked the console with inspector and did not find anything that would cause this. So something was different about those two types of fields. The options fields are draggable. The label fields are not.

I found this on Bugzilla:

As a work around, I discovered that if I hold the option key while selecting, THEN I could select text. Again, this is in FF. Support could not reproduce the issue. Likely they were on a different browser. I want to thank support for taking a look at this issue for me. I’m sharing in case anyone else experiences this issue.
