Pre-bug filing question on tab focusing issues

We are experiencing issues with tab focusing mishaps where the selected tab on a file if selected to view by when you type it types in a background tab. Usually fixes it self by a refresh at the browser level. This is quite a problem for us as very often you discover the issue quite late and you have polluted code.
We are using chrome, with theia built on a docker with the next package.json (the merge of the gitthub cpp+python package files); node version is v10.19.0.

  1. was it seen

  2. was is needed as far as logs to do a proper bug filing?

If you can create a bug reproducible from sources it would help.
