Error indicator lost when focusing and defocusing invalid required field

[macprzepiora]

To reproduce:

1. Create a text field that is required and has validation (see https://gist.github.com/macprzepiora/665597644c9e7b39c2746872a579f149 for a complete example showing the issue)
2. Run the app
3. Enter invalid value into the text field
4. Defocus the field
5. Focus again
6. Defocus the field again

Observed result: Error indicator disappears

Expected result: Error indicator is still shown

Also, the issue is not present when the field is not required

This (or something very similar) should have been fixed by vaadin/vaadin-text-field-flow#77. Please verify that you're using vaadin-text-field-flow 1.0.0.beta10 or newer?

I am using 1.0.0.rc1

As of 10.0.1, this is still reproducible. If you want me to, I can take a look into it and try to fix it

Closing. Seems to work on V14.4
