What's Wrong?

When using the Claude Code plugin for Visual Studio Code, I use the Sidebar mode rather than the CLI tool, and I open one of the dropdowns labelled "Thinking" it opens all of these dropdowns.

This causes my feed to jump location and often gives me a lot more to scroll through or information which I do not need from previous "Thinking" locations.

What Should Happen?

Only the dropdown I clicked on should open, giving me the information I specifically requested for that section of "Thinking" time.
