I put this question to our shaykh, ‘Abd ar-Rahman al-Barrak (may Allah preserve him) and he said:
The ruling on khulwah [being alone with the woman], which was mentioned by the jurists, does not come into effect as a result of this looking, because the condition of khulwah is that the man should be alone with the woman in a place in which it is possible for him to have intercourse with her. End quote.
Please see also the answer the question no. 118557 .
And Allah knows best.
