Adjustment of font size in cluster with horizontal scaling

The font size within the cluster only adjusts for vertical scaling but not for horizontal scaling. Therefore, if the candle gets narrower but not shorter, some numbers of the volume (or whatever is used for the cluster) get cut off.

In the first screenshot consider the number 1014. If I scale horizontally to narrow the candle, the 4 gets cut off and only 101 is displayed (second screenshot). This could be very misleading and lead to erroneous decisions.

I would wish for the font size to scale down (like it works for vertical scaling) to a size where the entire 1014 can be displayed.

The width of the candle does not solve this problem and is no workaround as well. The number only gets cut off at another point and is not prohibited.
