This very idea, as an example, is constructed without taking into account the broadening nature of the upward movement. To make it clear, let me share the chart:
It doesn't matter whether you use the semilog or arithmetic scale; the trend line is not broken. Just because an arbitrary line is traversed by an indecisive amount of price activity, it does by no means signal a continuation of the downward movement. On the other hand, I have to make it clear that the market in this situation MAY go downward, but it doesn't disprove my point. Whoever shorts the market because of the TL breakout shown in the OP is missing the point of the phenomenon of TL breakout. This is what I'm saying.
