Sample on JSFiddle: https://jsfiddle.net/xL581koz/

[Summary]
- After entering a value in input[type="date"], setting an empty string "" will cause checkValidity() to return false, despite the validityState values being correct. 
- So the form cannot be submit.
- No issues occur when using form reset to clear the value.

[Expected]
For the condition,
- checkValidity() returns true.
- The form can be submitted successfully.

[How to reproduce]
1. enter a valid value in the input[type="date"] of the form. 
2. set an empty string ("") to the input element in JS.
