Search block: The block gets selected after adding a media item on another block

Description

After adding the search block into a post, it gets automatically selected after adding or replacing media items on other media blocks like the image block.

Step-by-step reproduction instructions

1. Add a search block
2. Add an image block
3. Select an image to be inserted in the image block
4. Observe that after the image is added the search block gets selected

Expected behaviour

The image block should be kept selected after adding an image.

Actual behaviour

The search block gets selected instead of the image block.

In some cases, I experienced a crash although I couldn't reproduce the exact steps. What I saw is that the scroll begins to jump from one place to another very quickly and then crashes, my impression was that different blocks were requesting focus and somehow the app enters in an infinite loop.

@AmandaRiu I ping you here as I saw that you recently enabled this block in this PR.

Thanks @fluiddot, I'll take a look at this and see if I can figure out what is happening.
