After recent Opera updates, with adblocker still enabled and without exceptions added, legit mp4 videos are no more loaded and displayed on page.
Even with the site added to exception list, I get an unwanted behaviour:

• the legit video is finally loaded and can be played after several page refreshes
• the sound of legit video is muted (I have to unmute it manually)
• the page is populated with mixed frames of advertising (some displayed and playing, some black / masked)
• when scrolling down the page, even if the legit video is ended or manually stopped, a popup with the video appears on right bottom of the page and plays again (with sound), which is unwanted and annoying

Before the recent updates, with adblocker enabled and without exceptions added, all was ok (legit video loaded and playing (with manual start - no autostart) and no advertising on page).

Windows version: Windows 11 Home 25H2 (26200.7840)
Opera version: Opera One (128.0.5807.52)
Chromium version: 143.0.7499.194
Example site (which I have to add to exceptions): https://stirileprotv.ro/
Example pages:

Hope you can help.
