VSCode widget tabs opens new page

On the VSCode widget , when the action tabs are clicked. VSCode is tries to open up a new page on the browser with the address https://file+.vscode-resource.vscode-webview.net/ followed by the path location to the ipynb file. This might be resulting from how the tabs are built into React and how this interacts with the VSCode environment, whereas the Toggle button is directly built into ipywidget itself.

Temporary fix suggested by @tomsing1: Shift + arrow keyboard shortcuts work for moving between the tabs for now.

I've got a simular issue, but when using python remote in WSL.
In that case the error is a bit different, though I guess the issue is the same:

Though after clicking cancel on the dialog, in the notebook the correct tab is in view.
