Description of problem:

In stage.quay.io new UI,  if a string is too long to be displayed in a limited length and non editable text box,  this long string can't be displayed completely even after sliding  the mouse left or right in text box.  It's very unfriendly to users.

How reproducible:

Steps to Reproduce: Stage.quay.io new UI
1. Create a new organization and a robot account with a long name and a long description in stage.quay.io new UI
2. Create some repositories under this organization
3. Try to set permissions for these repositories under the robot account created in step 1

4. Try to check the robot account name and description in `Set repository permissions` popup. 

Actual results:

The robot account name and description can't be displayed completely in the non editable text box, even after hovering the mouse over it and slide it left or right . 

The same problem exists in getting credentials popup too.  

But user can get the complete string by sliding the mouse left or right in old UI. 

Expected results:

The complete string can be displayed completely by sliding the mouse left or right in text box, just as what  the old UI does.
