Shortcode aren't paste inline in paragraphs

[soivigol]

After updating to 6.5 WordPress version, when I go to paste a shortcode from the clipboard to a paragraph or other editable component, the shortcode opens a new block, but doesn't allow paste inline as before.

Here's a GIF

Additional information: @carloslongarela and I were tested on several installations and in some installations we had this problem, but in others not. We don't have common plugins or themes, where there is the problem. Ones are created with the Block Editor and other ones with Classic themes. Servers, languages and other configurations are different. We don't see any external resource that could cause it.
We tested in WordPress Playground, with different PHP versions, and we had the same error too.

my testing suggests the "source" when copying mattered - if i pasted [bracket] i am generic text [/bracket] from an unformatted source, it got converted, but when pasting from eg a word document or rendered on a page, it displayed as text

[bracket] i am generic text bracket

it also looks like html ([code]Hello <em>world</em>[/code]) can cause it to be converted to a shortcode block
