Office Excel macro not rendering correctly

Summary

Office Excel macro is not rendering attached .xls file correctly. Behaves better if scrolled down very slowly but still shows gaps and often loading (keep spinning) on the published page. When scrolled down quickly, doesn't render anything. Moving the scroller up/down renders the xls file content but they often disappear when scroller is stationary.

Environment

Confluence 1000.0.0-3667ef1ac6b

Steps to Reproduce

1. Edit a page and attach an Excel file with enough lines to scroller to show
2. Insert Office Excel Macro
3. Publish the page
4. Try to scroll down the in the macro display area

Expected Results

The macro should render the attached .xls file / chart/graph without gaps and smoothly.

Actual Results

Macro renders the file inconsistently with gaps, spinning wheel showing. Behaves better when scroller is moving real slow.

Workaround

Try "hard refreshing" the page with CTRL + F5 (Windows) or CMD + Shift + R (Mac).
