Pressing shift quickly after clicking and holding a frame handle deselects it
Say I have a simple rectangular frame that I want to resize (bear with me: I know I can use the black arrow but this is just an example). I choose the white arrow tool, select the two right-hand handles, click and hold one of the selected points, hold down shift to constrain the direction, then drag to the right. So far so good in theory. However, if I press shift within a few seconds of the click+hold, the handle I click on is deselected as if I had performed a simple shift+click.

I've checked Illustrator, and the problem doesn't occur there. I've never noticed this being a problem until perhaps a few months ago, so is this a bug that's been introduced with a recent update? It's been pointed out to me that if I reverse steps 2 and 3 I can sidestep the issue but that's not the point. I am used to doing it in the order I have described and it should work.
Again I forgot the computer specs. Windows 10, InDesign 13.1
