"Clickable=none" does not work for icon == custom

[Tragl1968]

Current Behavior

"Clickable=none" does not work, while using "icon=custom" with an icon. (I used Material Design)

In Dashboard:
If I click on the icon, the icon gets an "endless refresh circle".
Refresh of page does stop the "endless refresh circle".

This looks like "clicking an icon" is ignored by "Clickable=none"
See #1508

Expected Behavior

In Dashboard:
If I click on the icon nothing should happen

Steps To Reproduce

• Create a switch node
• Set Icon to "custom"
• Set Clickable to "none"
  --> GO in Dashboard:
• Click on icon, see "endless refresh circle"

Environment

• Dashboard version: 1.20.0
• Node-RED version: 4.0.3
• Browser: Chrome
