Broken: (example: 2.80, edbf15d3c044, master, 2018-11-28, as found on the splash screen)
Worked: (optional)
**Short description of error**
by default, front/back views and side views are orthographic, when you pan from these views, the view become perspective user. In 2.7x versions key 5 toggle from perspective to orthographic, then when you're in perspective view and you numpad view shortcuts, view remains with perspective and same thing with orthographic view whatever navigation you do, you keep the orthographic view.
In version 2.8 the toggling with numpad shortcut 5 from perspective to orthographic (and orthographic to perspective) view doesn't work properly in any workspace.
**Exact steps for others to reproduce the error**
Based on the default startup or an attached .blend file (as simple as possible).
