Allow text to show outside of the text frame when the last item in a Flex Layout
When a text box is used in a Flex Layout in a vertical orientation and is the last item, any letters that render below the base line (aka descenders -> y, j, p, q), the flex box trims the text making these letters unreadable. The only workaround is manually extending the text box height to include the descender. However, when done, this affects the spacing of the Flex Layout.
In a situation where you have individual items (example- a list of events) you want a uniform spacing between the event title, date, time, and location replicated across multiple events. For organization, you would have a parent flex layout (all events) and children flex layouts (individual events). Adjusting the size of the last text box to make the descenders visible affects the spacing of this event, in turn, affecting the spacing between all of the events in the list.
Currently, the Flex Layout seems to work best for a) non-text items, or b) text items with a non-text item at the end for vertically oriented layout. I don't see a situation where trimming text in InDesign is ever useful.
According to InDesign support, this is functioning as designed. I would believe this is a bug but posting to Feature Requests.
