Using PIE while in Paint Mode makes viewports not remember their settings

Bug description: When using any painting tools (Vertex/Blend Paint or Landscape Scult/Paint) the Unreal 4 Editor fails to remember old viewport settings if Play In Editor (PIE) is used while editing. More specific the viewport realtime mode is always enabled after exiting Paint Mode, if PIE mode was used while editing.

How to replicate:

  1. Open any old or new project
  2. Turn off realtime mode of viewports by pressing Ctrl+R (do
    this only if mode was on!)
  3. Add static mesh into world and enter Paint Mode by pressing Shift+2
    OR Add landscape into world and
    enter Landscape Mode by pressing
    Shift+3
  4. (note) Viewports are now updating in realtime as they should
  5. Now press Play or Right click scene and press Play From Here to go
    into PIE mode
  6. Exit PIE mode
  7. Exit Paint mode or Landscape mode
  8. Viewports are still set to update in real time, editor fails to
    remember settings because of PIE
    session in between

Expected behaviour:
After exiting Paint Mode the viewports should not be in realtime mode, if they were not in realtime mode when Paint Mode was entered. If you do these steps, but do not enter PIE mode in between, then editor remembers settings.

Not a very severe bug, but it bugged me for so long why I had to toggle Realtime mode off so many times while painting.

Version: 4.15.1

EDIT: Formatting is a bit off, dunno whats up with the list…
