**BUG**
Concise problem statement:
Steps to reproduce bug:
1. I open any package.
2. I'm trying to put the cursor in the field "Custom Attributes -> package".
3. I type a new name and it is not entered.
Results: Can't change package name.
Expected results:
Browser: Firefox 54.0.1 (32bit)
P.S. It is solved by keeping the left mouse button on the field and simultaneously entering a new name.
