How to reproduce:
1. Open the attached "1214048.zip" project and open the Profiler window
2. Enter Play Mode to begin profiling
3. Exit Play Mode and save profiling information to a file
4. Load the file that contains profiling information using the Profiler's 'Load' button. This will display the previously captured Profiler data in the Profiler window

Expected Result: The Profiler Window's record button stays toggled on
Actual Result: The the Record toggle is off (Does not reproduce for 2017.4.35f1)

5. Enter Play Mode

Expected Result: The Profiler begins profiling, data is shown in the Profiler window
Actual Result: The profiler window appears to not be profiling and the Record toggle is off (Does not reproduce for 2017.4.35f1)

Alternative Steps (particularly for 2017.4 and earlier):
1. Open the attached "1214048.zip" project and open the Profiler window
2. Enter Play Mode to begin profiling
3. Exit Play Mode and save profiling information to a file
4. Enter Play Mode
4. Load the file that contains profiling information using the Profiler's 'Load' button. This will display the previously captured Profiler data in the Profiler window

Expected Result: The Profiler loads the file and then continues profiling, data is shown in the Profiler window
Actual Result: The Profiler Window stops receiving new frames (and for versions after 2018.1, the Record toggle is off)
