Unable to set height to 0 when selecting multiple devices

[raphis]

Deployment Type

Self-hosted

NetBox Version

3.6.7

Python Version

3.8

Steps to Reproduce

1. Go to devices-type list
2. Select multiple device types
3. Click on "edit selected"
4. Try to add "0" as value for the U height
5. 0 isn't accepted as value

Expected Behavior

0 can be set as value for height when the device itself is modified so I expect the same behavior when editing multiple devices.

For non-rack devices I usually set the U height to 0.

Observed Behavior

Message when clicking on save: Value must be greater than or equal to 1
