Description of problem:

When the user opens the project access in developer perspective, the "Save" and "Reload" button are unaligned and the reload button does not work.

Prerequisites (if any, like setup, operators/versions):

None

Steps to Reproduce

1. Switch to developer perspective and select a namespace.
2. Open "Project" from the main navigation and switch to the "Project access" tab

Actual results:

1. The "Save" and "Reload" are not positioned at expected. Right below the data table or in the bottom left corner. Notice that there is also a success message after saving the latest role bindings.
2. When the user opens the "Project access" tab in another browser tab and updates the role binding in tab 1, the reload in tab does nothing.

Expected results:

1. "Save" and "Reload" buttons are position well. I personally would expect similar to most other forms now, that they are position in the bottom left corner and that there is a shadow if the table contains so many data that some are hidden behind this form footer.
2. When the user opened the page multiple times and press "Reload" in another browser tab, the user expects that the latest data are shown and overrides his changes.

Reproducibility (Always/Intermittent/Only Once):

Always

Build Details:

1. Cluster is running 4.7
2. Tested with latest console master (tested with commit)
