[Bug report] Tooltip Bug for Mixed chart type candlestick & line

Hi, thanks for the migration for the chart.js 3.0 .
I just found some bugs written in the title of this report.

please kindly check it through.

[what i done]
I made a simple mixed chart of candlestick and line chart

[bugs]

Here, the tooltips have some issue when pointing the mouse to the line chart.(it seems to be OK in the candlestick)

there is many errors occuring, and the tooltip freezes+ wont show the right data.
I assume that it has some compatibile issue with line chart {x: , y: ,} format and candlestick { t:,o:,h:,l:,c,} format

[code]
Here it is!
