Short Portal names are cut off

Steps to reproduce:

1. Open the attached project
2. Open the Test.texmkr graph asset
3. Select the Wire between "New Variable" and "UniformNode"
4. Right-click and select the Convert To Portals option
5. Delete the name of the Portal and observe the Portal node width
6. Change the name of the Portal to "Test"
7. Observe the Portal nodes again

Actual results: The Portal node width is shorter compared to when no name was set, and the name text is cut off

Expected results: Minimal Node width is ensured, so short Portal names are not cut off
