Event based outlook addin window.innerHeight returns 0

[elemen7s]

I have an event based Outlook addin with an ItemSend Event. When the user clicks on the Send button, I need to open a dialog using the displayDialogAsync. Since this only accepts a percentage for width/height I am calculating the ideal percentage based on the screen size for my content to fit without any scroll bars or extra space.

In javascript, window.innerHeight returns the value 0

In Firefox, even the window.outerHeight returns 0 while in chrome and edge, window.outerHeight returns the correct value.

Your Environment

• Platform [PC desktop, Mac, iOS, Office on the web]: Office on the web
• Host [Excel, Word, PowerPoint, etc.]: Outlook
• Office version number: Version 2305 (Build 16501.20242)
• Operating System: Win 11
• Browser (if using Office on the web): Edge/Chrome/Firefox

Expected behavior

Expected behaviour is to have the correct values in the window object. Outlook should not change any of the original values of the window object or if it is being copied, all properties should be copied accordingly so that the correct values are used inside the addin.

Current behavior

Current behaviour is that window.innerHeight returns 0

Steps to reproduce

Any addin with any event such as ribbon button click or on send Call window.innerHeight Check value
