The saving location issue is fixed in the latest updated. However, the minor issues I also reported are still present. No keyboard focus on the window to allow pressing Enter to save. Zoom is blurry and pixelated. There is still a browser right-click context menu over the dialog, and you can still drop in arbitrary files into the window and have them open.
I've logged an issue for the export as folks to fix the browser behavior issues.
I'm not able to repro the blurry zoom. Could you create a new topic and post some screenshots of what you're seeing and steps to reproduce that? (easier to track issues separately) Thanks.
Here are some screenshots showing what I mean. In the previous version of Photoshop, the preview quality was much better.
Below is what this design looks like at 100% scale in the Export As dialog.
And below is what it looks like at 33.33%. I know odd percentages like that don't normally look good, but this demonstrates the issue more than it would at 50%. The preview is notably pixelated as seen by the loss of pattern detail, but it's also blurry on top of that.
