I have a problem in displaying lightning:icon in Lightning:tabset after the release of Winter 19, the Lightning:icon is not displaying an image. Here's my code:
<lightning:tabset variant="vertical">
<lightning:tab>
<aura:set attribute="label">
<lightning:icon iconName="utility:unlock"/>
Authentication
</aura:set>
<aura:set attribute="body">
<c:AuthenticationComponent/>
</aura:set>
</lightning:tab>
</lightning:tabset>
This code is working but after an update of Winter '19 icon is not displaying.
label
attribute fortabset
. You should get compile time error with this code?
