Find-on-page sidebar feature disabled on 129.0.2792.52 Stable

Hello, with the latest update to 129.0.2792.52 Stable the Find-on-page sidebar feature got disabled completely.  Now there's only the old and very limited pop-up box left for in page searches. 
Also all the flags related to find-on-page are gone:

edge://flags/#edge-sidebar-find-on-page

edge://flags/#edge-find-on-page-filters

edge://flags/#edge-related-matches-for-find-on-page

We noticed that this happened on the other channels before (Beta, Dev and Canary) when they switched to version 129. 

The Find-on-page sidebar is a stand alone feature for chromium based browsers and we use it a lot for researches. Especially the list of find occurrences is a big enhancement for navigating through long texts. 

Can someone from the team please give information if the Find-on-page sidebar got finally deprecated or just temporarily disabled for experimenting and will be available in the future soon?

Thanks in advance!
