PS 2019 Missing selection when changing to bitmap mode

[cm_lyokosk]

Hi, I have a problem

When I change image from Grayscale to Bitmap mode, the selection is missed. 

How can I keep the selection? Please help. It's not happen with older versions.

Thanks a lot.

As a work-around try Select > Reselect (cmd-shift-D).

It's working. Thank you ^^

 I tried in Photoshop CC 2017 and there the Selection also disappears at conversion to Bitmap. 

Do you remember in which version the Selection was maintained?

I used it in 2017 ver too.
