pButton | Loading icon not removing

Oh no, more problems with buttons :(

Using p-button might break some styles, a work around this is to supply loadingIcon, something like this:
`
<button
pButton
type="button"
icon="pi pi-search"
loadingIcon="pi pi-spin pi-spinner"
[loading]="loading"

`

I can confirm this issue. In my case it was the other way round, the spinner did not show up despite the loading property changing from false to true.

When supplying the loadingIcon as @knightSarai mentioned, it works.

When setting the loading property to true, it still disables the button. If setting the property to true before the button is rendered, it also shows the spinner.

Maybe there is some issue with change detection here?
