Logger is not logging every blocked element on reddit.com

[JohnyP36]

Prerequisites

• I verified that this is not a filter issue (MUST be reported at filter issue tracker)
• This is not a support issue or a question
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
• The issue is not present after wholly disabling uBlock Origin ("uBO") in the browser
• I checked the documentation to understand that the issue I report is not a normal behavior

I tried to reproduce the issue when...

• uBO is the only extension
• uBO with default lists/settings
• using a new, unmodified browser profile

Description

See uBlockOrigin/uAssets#13072 (comment)

The point is: on reddit.com the logger doesn't log every blocked element

It only log the element from other domains (3p).
But if I turn on the DOM-inspector tada! you see there are elements blocked

A specific URL where the issue occurs

reddit.com

Steps to Reproduce

1. Open the uBlock Logger
2. Go to the homepage of reddit.com - just https://www.reddit.com/
3. Scroll down the page for a while on reddit; don't click on posts; just scroll slowly down.
4. Go back to the logger and notice that from the block element only ###ad-overlay from streamable.com is blocked.
5. Switch in the logger to DOM-inspector
6. See that multiple elements are blocked and not only the one stated in point 3.

Expected behavior

The Logger has to lock all blocked elements on the page.

Actual behavior

The Logger only logs blocked elements from an in the webpage inserted third party element,
but not the 1p elements.

uBlock Origin version

1.42.2

Browser name and version

Not sure if I understand correctly or not, but I can see the first party logs as normal.

I double checked it. It seems there occurred an one time error, because now the Logger logs everything.

However, it's strange that this happens.
