Steps to reproduce the behavior

PrimeNG 16.6.0:

• Select a city => the other cities become disabled (normal since selectionLimit=1).
• Deselect that city and focus out => the floating label comes back down.
  => Pass

PrimeNG 17.0.0:

• Select a city => the other cities don't become disabled (they should since selectionLimit=1).
• Deselect that city and focus out => the floating label doesn't comes back down (it should). Deselect that city and focus out => the floating label comes back down.
  => Fail

Expected behavior

Should work as PrimeNG 16.6.0
