Adding a directory in the browser session via local drag/drop does not work

[toddewilliams]

Describe the bug
As a participant using a browser, adding a directory containing files to the shared file tree via drag/drop does not work with Eclipse or IntelliJ hosts.

To Reproduce
Steps to reproduce the behavior:

1. Start a session.
2. Join a session in the browser.
3. As a participant, just try to add a folder containing files inside the project in the explorer via drag and drop from the local.
4. Uploading of those files starts & just wait until it finishes.

Actual: Files with the directory are not added into the explorer or it just fails without any message.

Expected behavior
Expectation is for the directory and files to be created in the shared file tree and uploaded to the host IDE.
