First pages of book do not display - MacOS Safari

[bluefirepatrick]

There is an issue where the first pages of a book will not be displayed in ts-toolkit test app/vanilla on Safari for macOS. Resizing the browser window fixes it.

Chrome for macOS and Firefox for macOS do not have this issue.

Steps to repeat:

1. On Safari 18.2 (latest) for macOS Sequoia 15.2 (latest)
2. Clone and run develop branch of go-toolkit.
3. Clone and build develop branch of ts-toolkit.
4. Change line 25 of testapp/vanilla main.ts to: publicationURL = "http://localhost:15080/bW9ieS1kaWNrLmVwdWI/manifest.json" so that reader loads Moby Dick from go-tookit.
5. Open the reader via http://localhost:5174
6. The first page of the book will not show up and paging forward will show blank pages for the next four pages.
7. Reload the reader. Again, the first page does not show up but resize the browser window; the page shows up and subsequent pages also display.

@bluefirepatrick FYI you can just include the parameter in the URL, and you won't have to change the code, so http://localhost:5173/?book=https%3A%2F%2Fpublication-server.readium.org%2FbW9ieS1kaWNrLmVwdWI

@bluefirepatrick I am unable to reproduce. See the screenshot:

Is there any other detail you could provide?
