UITableViewCell.layoutSubviews sets tintColor = .systemBlue (or nil) to it's accessoryView

I have a subclass of UITableViewCell which sets a custom YPButton (subclass of UIButton) to accessoryView.
According to the attached screenshot, UITableViewCell.layoutSubviews calls `_updateSystemTypeAccessoryView:withCellAccessoryType:forState:` which sets accessoryView.tintColor = .systemBlue (or nil).
It makes my buttons blue.
I don't expect that, I expect my buttons grey as I set tintColor before setting accessoryView.

I've already found a workaround:
I set UIView with my button inside.
