The first and main bug, about which I wanted to report that the authorization window got under the video from the news feed and it became difficult to enter the authorization data.
Screenshot and another bug that occurred while describing this.

Authorization window climbed under the video
During the first attempt to write this post, I realized that I did not take a screenshot and saved the post in a draft. After I wanted to continue editing the post, I was very surprised when I ran into the second bug:
In the "new" tab, Habr reports that I have 1 published post and one in the drafts:

One published post and one in drafts
But for some reason, the situation has changed in the drafts and the post that I have already published a long time ago is displayed here now, but it seems that there are no more published posts (confusingly, but see the screenshot):

Published post climbed into drafts
')
And I didn’t like that when inserting the next image, I’d have to manually delete the information about the previous one.
