• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.

• I have tried creating a repro with https://new.docusaurus.io.

Description

Tab sync does not seem to work, even when Tabs blocks have a similar groupId. This issue is present across latest Firefox and Chrome, and happens within the Docusaurus documentation itself.

Reproducible demo

https://docusaurus.io/docs/markdown-features/tabs#syncing-tab-choices

Steps to reproduce

1. Go to the docusaurus docs website, markdown-features/tabs section
2. Try clicking the examples in the Syncing Tab Choices portion

Expected behavior

The tabs for windows/mac should change in sync.

Actual behavior

The tabs are unaffected by selections of one another.
