CMS 5.3.0-beta1 regression: "Failed to load link" with anchor links

[GuySartorelli]

When adding a link to a "page on the site" with silverstripe/linkfield inside an elemental block, we get this error when publishing (unclear if it's publishing the page or the block)

Failed to load link(s)

Note that the correct link displays after refreshing the page.

Steps to reproduce

Note this assumes you have silverstripe/frameworktest installed, along with the rest of kitchen sink.

1. Add Link List Block
2. Go to Single Link
3. Select Add Link
4. Select Page on the site from dropdown
5. Select a page
6. Add Anchor
7. Select Update link
8. Link should display in DRAFT mode
9. Select Publish

Can reproduce this - though some of the steps are a bit odd (why does it say "update link" in the instructions when you haven't even created it, for example?)

[GuySartorelli]

Frustratingly cannot reproduce this locally.
The environment I am able to reproduce it in is https://cmstestm-prod.sites.silverstripe.com/ which is PHP 8.3

[GuySartorelli]

I suspect it is a result of this:

The correct URL is https://cmstestm-prod.sites.silverstripe.com/admin/linkfield/data?itemIDs[]=95 (which it does eventually try) but for some reason the ID is split into two for the first request (https://cmstestm-prod.sites.silverstripe.com/admin/linkfield/data?itemIDs[]=9&itemIDs[]=5)

I'll try reproducing locally with IDs in the double digits.

[GuySartorelli]

Can reproduce locally now - getting the exact same split ID problem when running in my local with double-digit IDs.
