A flow action containing a legacy list view layout has been refactored to include a section containing a table layout, which is populated from a report definition executed from within the flow action's pre-activity. However, the layout is expanding to the right, outside the bounds of the 'parent' flow action layouts (see highlighted area in screenshot). I've tried both including the layout as a section, and also as a section reference within a dynamic layout, but the problem persists. On inspecting each column definition, the width is also being hard-coded, even if the values are blanked or changed to smaller column widths, so I'm unable to condense the layout to mitigate the issue.

Has anybody seen this before?

Many thanks.
