Rorohiko’s FrameReporter might help. The item’s geometric bounds don’t appear to be one of the many things Frame Reporter can show, but I’ll bet it could be added by modifying the script. Kris has an email address at the bottom of the Frame Reporter page inviting users to request other things to report.

The best practice here is to NOT override master page items on document pages. Build the master pages so they only contain objects which remain intact (other than changing automatically, like Current Page Number placeholders) as is on document pages. I know that’s not possible 100% of the time but it should be the goal, especially if you need to add single pages to a facing-pages spread more than a couple times.

That means:
1. Use Primary Text frames on the master pages, with NO text in them. These don’t have to be overridden on the document pages. If you insert a single page and a left-facing page ends up on the right, and you have different columns/margins for left and right, you can easily reapply the correct master and not end up with overlapping text frames.

2. Use dynamic text features on master pages whenever possible. For example, instead of typing in placeholder text for headers (which must be overridden and entered manually on doc pages), insert and format a Section Marker there (Type > Insert Special Character > Markers >) and then when a header changes for a new section, use Numbering & Sections on that doc page to change the section name.

3. For all other items that need to appear in the same location on various pages but customized for that page, create a Library item or a Snippet, which remember their locations, and base them on an object style whenever possible. Example: photo credit text frames, pull quotes, image captions, images with caption, order form, placeholder ads, etc.

Caution: no solution offered in this post. ;-\ Just commiseration …

Ouch! Weird!

Hrm. It has to be a new glitch otherwise we would’ve encountered it already … Alt Layouts have been around since CS6.

Erica Gamet does a lot of work w/the feature … could be worth a ping to her.

What does this mean: “but when that text was copied to the EPUB format”

Are you saying you copied/pasted text to a new INDD file?

If so I’m guessing your prefs in the target file are set to create typographer quotes. (Preferences > Type > Use Typographer’s Quotes). That is the default setting.

The answer is to make sure the target document has the option disabled before pasting in something with straight quotes.

Also, if the deed is done already ;-) you can use Find/Change to find curly quotes and replace with straight quotes … in the Find field, click the flyout menu of the special characters and choose Quotation Marks > Straight Single (or Double).

You made a JPEG out of one of the pages and placed it back into the document?

Sorry, not following you.

The CircularFLO utility can convert InDesign path text to selectable text. It’s $199/ebook and only creates fixed layout epubs and mobi’s, but you can use a free trial to create 10 pages worth to test out.

ah … and suddenly it’s quiet. Interesting!
