System Information
Operating system: Windows-10-10.0.17763 64 Bits
Graphics card: GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 390.77

Blender Version
Broken: version: 2.80 (sub 58), branch: master, commit date: 2019-04-23 17:06, hash: f32902e6da
Worked: (optional)

Short description of error
When focus is stolen (for example, when the user uses Ctrl+S and the file browser dialog pops up), a running modal operator will lose the context.area and it never returns even after the dialog has been closed.

Exact steps for others to reproduce the error
Run the attached modal operator from a VIEW_3D area, without pressing RMB or Escape (which will cancel the operator), bring up the Save File dialog. Watch the console output- it will change from VIEW_3D to "no context area" because the dialog has focus and the area is no longer valid, but when you Cancel the file save operation, you would expect the context.area to return but it never does. You must cancel the operator and restart it.modal_area_focus_bug.py

Will consider that as a known issue for now, I suspect that won't be trivial to fix (file saving is also an operator, I don’t really have an idea of how modal ops are supposed to be handled in those cases…).
