Sorry I have no idea how you managed to get Acrobat to show a pop-up when including a PDF. On my system it refuses to do that and shows only a small dashed rectangle. So I can't test your issue but I assume that it is a Acrobat issue and that you should report it there.

I used Texlive 24 and lualatex-dev.exe for compiling the document. No other method I used to create the pdf. I faced another issue, I used only gray background image for testing that time pdf not shown the alt text. At the same time if I used png image, the pop up showing correctly

I corrected the pdf manually wherever the figures in the top position of the page
