Component: dropdown - Editable dropdown does not change value to empty string

[ppieczul]

If one of the options is empty string, when selected from the dropdown, the content of the editable box will not change to the empty string. I believe the culprit is this condition:

Thanks a lot for your report and hint! We'll check it before the next version is released.

This solution breaks the placeholder text.
Try clearing a selected value in your example, https://primeng.org/dropdown#template

I noticed the same thing as @jayee

primeng/src/app/components/dropdown/dropdown.ts

Line 154 in f305b27

<span *ngIf="(modelValue() === undefined || modelValue === null) && (label() === placeholder || (label() && !placeholder))">{{ label() === 'p-emptylabel' ? '&nbsp;' : placeholder }}</span>

Maybe there should be
(modelValue() === undefined || modelValue() === null)
instead of
(modelValue() === undefined || modelValue === null)

Just confirmed, this is a bug - no placeholder visible, missing brackets in code
