How to avoid page resize with a blank section in the bottom when clicked on a button

Browser: IE11

OS: Windows 7

TestComplete: 11.10

Test Type: Functional Web testing.

Able to find the Object but when try to perform some operations like, ScrollIntoView or click the page resizes with scroll buttons look different as show in the attachments. It is not happening when performed this operation manually.

If anyone has an idea please let me know at your earliest.

Note: Recently I am noticing this it wasn't an issue before. It happens with recorded actions by TestComplete.

Button details: it happens only with this button and dev team says this button is same other buttons.

<INPUT name=ctl00$btnEdit class=button id=ctl00_btnEdit onclick="this.disabled = true; this.value = 'Edit...'; ShowSpinner(true,'loading');__doPostBack('ctl00$btnEdit','')" type=button value=Edit>
