Describe the Bug

I want to mark an icon as optional, i.e. the component should not raise an error if the icon does not exist in the iconDir directory. Currently if such an icon is referenced, the error takes over the whole page:

What's the expected result?

The component should log the error but not take down the entire site like it does currently.

What's the use-case of an optional icon?

[dhruvkb]

I have icon names coming from an API where I want to supply some icons but let other icons be silently hidden.
