Issue Summary

When a table is nested within a Page Properties or Expand macro, switching to page edit mode resizes/widens all table columns on the page. This is true for all tables if it's  nested in one the aforementioned macros.

This makes editing multiple tables/macros on a page take significantly longer as every column in each table must be manually resized to a view that properly displays all table data.

Steps to Reproduce

1. Add the Page Properties or Expand Macro to a page
2. Add a table with 2 to 3 columns inside either macro
3. Publish the page
4. Choose Edit
5. Select either macro's (Page Properties or Expand Macro) page elements so the right side panel for that macro opens. Notice that the table columns are significantly expanded to the point that horizontal scroll bars now appear beneath the tables.
6. This table behavior is also reproducible if a macro on the page is deleted or if a divider is added to the page.

Expected Results

Edit mode shouldn't modify the table widths.

Actual Results

Table column widths are significantly widened when editing or deleting macros on the page.

Workaround

Zooming out via your browser controls (Command +/- or Control +/- on Mac or PC respectively) prior to making edits reliably works around this issue.
