Reproduction steps:
1. Open the attached project named Case_1197494
2. Open the SampleScene
3. Enter Play mode
4. Observe 15 messages in the Console window
5. Enter any value into the search field to filter out all of the messages
6. Check if "Maximise on Play" setting is enabled
7. Play the scene again
8. Check the console window

Expected result: The value in the search field remains to show how messages are filtered
Actual result: The search field is cleared, however, the messages are still being filtered by the old value

Reproducible with: 2019.1.0a11, 2019.2.12f1, 2019.3.0b11, 2020.1.0a14
Could not test with: 2017.4.34f1, 2018.4.13f1, 2019.1.0a10(Console filtering option was not available)

Workaround: Entering any symbol into the Console search bar will reset it

Notes:
1. The console filtering option was introduced in 2019.1.0a11
2. For the issue to occur the Console window must be docked and "Maximise on Play" setting be enabled
