File tree container height doesn't change after it was resized on Activity page

Steps to reproduce:

1. Open https://atlaseye.atlassian.com/browse/bamboo-git/bamboo-acceptance-test/testng-deployments2.xml
2. Change the file tree browser component width
3. Expand some folders in the same component - the content would go below the end of it and would render on the footer

The issue found in 3.9.0, but seems like it's an old one.
