Description

the original demo would fail after switching to the 3rd tab once, by not returning to it again when directed to.

It appears that somewhere in tabs, that selected is not being updated when a tabitem is selected.

relevant motivation:

• to be able to change to and fro any tab I would like programmatically

a summary of the change

• updates gr.Tabs state to reflect the currently selected tab after gr.Tabs.update(selected)-

which issue is fixed.

• not being able to activate the tab programmatically again if you select some other tab with the mouse first.

any additional dependencies that are required for this change.

Closes: # (issue)

A note about the CHANGELOG

Hello 👋 and thank you for contributing to Gradio!

All pull requests must update the change log located in CHANGELOG.md, unless the pull request is labeled with the "no-changelog-update" label.

Please add a brief summary of the change to the Upcoming Release > Full Changelog section of the CHANGELOG.md file and include
a link to the PR (formatted in markdown) and a link to your github profile (if you like). For example, "* Added a cool new feature by [@myusername](link-to-your-github-profile) in [PR 11111](https://github.com/gradio-app/gradio/pull/11111)".

If you would like to elaborate on your change further, feel free to include a longer explanation in the other sections.
If you would like an image/gif/video showcasing your feature, it may be best to edit the CHANGELOG file using the
GitHub web UI since that lets you upload files directly via drag-and-drop.

Hi @TashaSkyUp thank you for the contribution! This looks good to me and I verified it fixes the problem. Can you please add an entry to the changelog and regenerate the demo ipynb files? I will merge afterwards!

@freddyaboulton Thanks, unfortunately I just don't have the time to setup the full development environment. But I'll try to get around to updating the ipynb files manually

No worries @TashaSkyUp ! I made the modifications to your branch. Thanks for the contribution!
