Hi,
I'm finding there is a bug or several bugs with IE brower when configuring popups to use the docking positions (using 4.10). I created a simple demo app, and specified created the mapView like this:
app.mapView = new MapView({
container: "viewDiv",
map: map,
center: app.center,
popup: {
dockEnabled: true,
dockOptions: {
// Disables the dock button from the popup
buttonEnabled: false,
// Ignore the default sizes that trigger responsive docking
breakpoint: false,
position: "bottom-center"
},
collapseEnabled: false
},
zoom: app.zoom
});<SPAN class="line-numbers-rows"><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN></SPAN>This causes the popup to default to the specified dock position. It works fine in chrome and other browsers, but in IE, most of the dock positions cause a bug. Below is the screenshot for bottom-center:

Other positions have similar issues, including content overflowing popup container, and for bottom dock positions, the position is shifted to the right (bottom-center and bottom-right).
I have been messing around with css to fix the issue but not much luck so far. I'm attaching a word doc with images of the different doc positions....
I'll report this as a bug, but if anyone has thoughts about how to work-around this in the meantime, great. I'd prefer for my app to specify bottom-center.
Thanks
