@tombrunet Noticed that the line if (path && path !== devtoolsState!.lastElementPath) was commented out in a previous PR. Without it, setSelectedElementPath is getting triggered multiple times, leading to unintended focus shifts. Re-enabling this line resolves the issue and stabilizes the focus behavior as expected. Please let me know if this caused any issues previously, and I'm happy to look into alternative solutions if needed. Thank you!

Need to test more

Not clear why that was originally commented out. Will try to do the various focus scenarios and see if anything crops up.
