• In Chrome, the copy page action does not work, but the move page operation does.
• In Firefox, the page will be slow to edit and copy, but it does work due to the size of the page and does not throw the "RangeError: Maximum call stack size exceeded" in the browser's console tab.
  No errors/exceptions are seen in atlassian-confluence.log and atlassian-synchrony.log logs.
• The issue happens irrespective of Collaborative editing status.
• Increasing Synchrony and Confluence heap does not help.

Workaround

• Use Firefox browser to work with the page having a large table having issues in Chrome browser. If editing in Firefox also shows a blank screen with a "Ready to go" message in the bottom bar next to the Save button, export the page as a Word document, reimport it to create a new page, and try to edit in Firefox.

Note:
Following Too Much Recursion Or Maximum Call Stack Size Exceeded Error In Browser Web Console does not resolve the issue. The issue happens with the Vanilla Confluence instance.
