Error message when opening some books in ebook-viewer

[odamizu]

Hi! I'm getting this error message when I open some (but not all) books in ebook-viewer on macOS Sonoma 14.6.1. I think it started with 7.17.0.

calibre, version 7.17.0
ERROR: Unhandled error: Unknown error

Traceback (most recent call last):
at IframeBoss.update_toc_position (userscript:viewer.js:29477:31)

at ensure_page_list_target_is_displayed (userscript:viewer.js:20279:24)
TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'.

When I click "Okay" the error message disappears and I can read the book without problem.

I don't understand the error message and it's not stopping me from reading the book, but I thought I'd mention it.

Let me know if there's any more info I can provide or testing that will help.

It's already fixed you can use the preview release or wait for the next official release.
