Some of the modebar options are not displayed

Hi, I am seeing that plotly js modebar is getting rid of ‘zoom2d, pan and couple more’ options. I didnt specify in any place for modebar buttons to get deleted, i dont realise why this is happening. It only happens when chart has one signal, if it has more than one signal, all buttons are visible.

That shouldn’t be happening. Can you share a reproducible example to help us debug?
