Gitpod webpage unresponsive when trying to close the "Preview" pane

[bogniq]

System config
OS: macOS 10.15.5
Browser: Chrome 86.0.4240.183 (not using Gitpod extension)

Steps to trigger the problem:

1. Follow each step in the "Instructions" section of README.md. After running gp preview $(gp url 8000), the Preview pane is opened and display the frontend webpage.

2. Try to close this panel by clicking "Close" on the context menu.

3. The webpage for Gitpod becomes unresponsive. I need to close this weppage and restart the Gitpod workspace to make it work again.

Other notes

• I'm new to Gitpod and eosio-web-ide. So I'm not sure if this problem is caused by Gitpod itself or some config here.
• If other user gets the same problem, one workaround is to use external browser for the frontend webpage (in "Open Ports" tab -> "8000", select "Open Browser").

This seems to be a Gitpod issue. We are closing it to focus on other priorities. Please reopen if needed.
