In regular expressions and icon mapping (forms where inline validation is introduced but forms are not opened as popups) when creating a new element and cancelling creating without clicking anywhere else, inline validation is triggered for name field. easier to see with 3G throttling.

Example: regex_cancel.mp4

Steps to reproduce:

1. In your browser set throttling to 3G (Developer tools -> Network -> change "No throttling" to 3G)
2. Open Administration -> General -> Regular expressions
3. Create new regular expression (click New regular expression)
4. Click Cancel

Result: inline validation is triggered, error message "This field cannot be empty." is shown until the form closes
Expected: form closes with no errors
