Max Histogram size not reset when Trades Column is Reset using "Clear trades columns" hotkey

Currently when the Trades column is reset using the hotkey, it seems like the maximum size is not reset as it is when using the X to manually clear the column(s).

Screenshot here shows two ladders in the same state:

Screenshot below shows left ladder reset manually, and right ladder reset using the “Clear trades columns” hotkey.

Note the histogram size disparity. Left is the expected behavior when using the hotkey.
i.e. The max traded size since reset is 13 at the bid, and 6 at the offer, so they are colored 100%.
