Hi all,
We recently deployed Edge to our organization, and while most things are working great, we noticed some strange behavior that got introduced in v84 when Edge gained the ability to remember a user's zoom preference on IE Mode sites.
We have several web apps we run in IE Mode that use an onclick window.open to display a PDF in a new popup window. Here is an example that would (hopefully) allow you to duplicate the issue:
<input type="button" onclick="window.open('test.pdf', '_blank', 'resizable');" value="click me" />
When the user clicks the button, the zoom level is automatically adjusted. If the parent site was on the same subdomain as the new popup, Edge saves the new zoom setting as their preference. So the next time they load the parent site, it is zoomed out relative to their preference. It seems like the amount the zoom is adjusted depends on the user's display scaling. At 100% display scaling, you may have to adjust the zoom to a value higher than 100% to notice the change.
I have gone through all of the document display options in Adobe Reader to try and keep this from happening, but even if I match the desired zoom level in Reader or specify Actual size, Edge zooms out when the window loads. We use Reader 2017 normally, but I tried with the latest Reader DC and got the same result.
Interestingly, if I create a test page with the window.open method above and call another web page rather than a PDF, it opens fine without zooming out. So I believe this is specifically related to Edge's handling of the Reader plugin through IE Mode and not window.open itself.
Anyone else noticing this issue, or any insight from someone who works on IE Mode?
Thanks,
Andrew
