The sense of deja vu was ended in style a few minutes later, when Fishlock picked up a Ukraine clearance 25 yards from goal and unleashed an unstoppable strike into the top corner.
The strike moves Fishlock to within one of Helen Ward's all-time Welsh record of 44 goals.
Ukraine, who had barely strung a pass together in the second half, were forced to be more adventurous in the closing stages, and the seven minutes of injury time added on was met with a few gasps from those in the Welsh dugout.
Wales were fortunate to not concede when Gemma Evans' defensive header crashed back off her own post, but in the final minute of the game Ukraine found the equaliser they were so desperately chasing.
The yellow shirts flooded forward, and from a whipped-in cross substitute Nicole Kozlova stooped down at the back post to place a thumping header into the top of the net.
Much like in the first of these two matches, Wales will leave with a sense of 'what if', having wasted a number of chances to put the game to bed.
Wales manager Rhian Wilkinson told BBC Radio Wales: "If you lose [a lead] in the last seconds of a game, it's always going to feel like a loss.
"It was a tough camp for us, an important camp for us, because as I said to the team, they are not the [type of] performances that are going to help us make history. We know that.
"It's not the window we wanted at all. We came here for six points and we leave with two. But maybe it's the one we needed because it's not good enough.
"I think a big positive is that we went behind in both games and we came back. That's something about [the squad's] character which I like. But [when] we are 2-1 up in the last seconds of a game we can't [concede].
"The players need to go away on holiday, unwind, recharge and come back in ready to work because we have another very important window to come."
