Input_number no more modifiable

Sime 0.79 my input_number are no more modifiable, they appear empty without any value:

inputnumber

Conf is pretty simple:

input_number:
  temp_for_morning:
    name: "Winter Morning"
    min: 12
    max: 25
    step: 1
    icon: mdi:thermometer
    mode: box
    unit_of_measurement: "ºC"

In the dev panel it has a value but it cannot be modified

reload your cache, ctrl+f5

Does nothing. Even complete cache clear does not fix this issue. Issue found on github: #16957
