Photoshop not recognizing pixel dimensions correctly when ppi differers

I have a small photo - 600x600 px set to 300ppi. I created a new file in Photoshop - 600x600px 72ppi. I dragged and dropped from my mac - with a regular monitor and from Windows Surface and got the same results. It comes in small and the options bar claims it's at 100%. The pixel dimensions should be the thing that matter - not the ppi.

There is a different understanding of the word size 100%. When Photoshop was created it was conventionally physical size in cm or inches.

Even nowadays Photoshop takes rather physical size than dimensions in pixels to calculate the percentage. It was acceptable in some cases when you for example need to place exact same sized human faces on the A4 canvas. But it's only one preference and it doesn't work like this with web and rgb images. after we got a dosen of different "retinas" x2 x3 x4 etc this PS behavior of calculating the placed image's size only using its physical size is absolutely outdated and needs to be reworked. Even screenshots on the same machine can be in a different resolution depending on the monitor they was took from.

Conclusion the photoshop must take into account the units used for the document we have to paste in
for pixels and rgb - 100% means 100% of pixels
for physical units - 100% of cm inches or whatsoever.
