Copy button overlaps expand/collapse arrow on MCP tool call inputs in chat

[ethoburn-bhep (ET BHEP)]

Describe the Bug

In the chat panel, when an AI tool call is made to an MCP server, the tool call input (showing the arguments/query sent to the tool) has a copy button that overlaps or covers the expand/collapse arrow. This makes it impossible to expand the input to read the full query.

Steps to Reproduce

Have an MCP server configured and active
Trigger any MCP tool call from the AI (e.g. a BigQuery execute_sql with a multi-line SQL query)
In the chat panel, locate the collapsed tool call input block
Attempt to click the expand/collapse arrow to read the full query
The copy button intercepts the click — the input block cannot be expanded

Expected Behavior

Expected behaviour The expand/collapse arrow on MCP tool call inputs should be independently clickable and clearly separated from the copy button.

Actual behaviour The copy button sits on top of the expand/collapse arrow. The input block cannot be expanded to view the full query.

Hey, this is a known bug. The Copy button overlaps the chevron on MCP tool call inputs. It’s already fixed, but the fix hasn’t made it into the stable release yet. It should land in one of the next updates.

For now, as a workaround, you can click the tool call block title itself (not the chevron) to expand or collapse, if that works for you.
