Mousing over aliases on disabled rules makes hint difficult to read
Mousing over aliases and other elements in a firewall rule set pops up a hint showing the contents of the alias.
Doing so on a disabled rule causes the popover to use the same translucency as the disabled rule creating a hard-to-read result.
Should consider making popovers 100% opaque even on disabled rules. I don't know if an opaque popover is ever desired.
