The compound above serves as an example where even though a pi bond delocalization pattern is present, it is not always necessary to factor in the effects of proceeding with such delocalization as that could produce a less stable aromatic configuration. The opportunity for pi bond delocalization is present in the ring above due to the s-trans configuration of two pi bonds, but proceeding with the delocalization would make the heterocycle have 8 pi electrons making it antiaromatic, which is extremely unstable. Rather, we can simply analyze the aromaticity of the heterocycle (or the 7-membered ring also contained within the compound) and see that it is already aromatic without delocalizing any pi bonds, thus making the entire compound be considered aromatic.
