Invalid format errors does not appear in Edit Screen when scripted fields are present

Summary

If scripted fields are present, then any errors related to invalid field formats (for example, inputting text in a number field) would not show up. Rather, the screen tries to load and just doesn't show anything.

Steps to Replicate

1. Set up custom fields that only accept certain formats (for testing I used number field and date picker field)
2. Include them in a ticket also contains scripted fields
3. Try to input the invalid format into the custom fields (such as entering text into the number field)
4. Try to update the issue

Actual Results

An error shows up in the browser developer tools instead.

In this example, PICKER 1 and PICKER 2 are scripted issue picker fields

If there are no scripted fields present, then the invalid format errors would appear as per usual :
