How a Readonly Property Wrecked My Letta Desktop Performance

Are you telling me a readonly property is wrecking my performance?

I discovered that a simple script using scrollHeight to auto-scroll new messages in Letta Desktop was causing severe slowdowns. I assumed this readonly property was static and fast, but accessing it forces expensive layout recalculations every time. Instead of calculating the exact height, I switched to a large fixed number to maintain performance.
