[v-hozha1]

Describe the bug
If we copy chars from the cell or notebook and then paste into filter field, the copied chars unable to pasted into filter field for both using hotkey Ctrl+ V or right-click 'Paste' button. Sometimes, it pastes this cell again or it pastes the below one markdown in the *.dib file.

Note:

4. Copy test123 and paste the strings into Polyglot Notebook variables - filter field.
