Problem with multiline search

// bellow is a line

:CtrlSF 'a line' works fine:

4 matched lines across 1 files. Done!

a line

// bellow is a line a line

a line

However :CtrlSF -R '//.*a line'.*\n.*a line.* prints file with match, but doesn't count it nor highlight:

0 matched lines across 1 files. Done!

a line

// bellow is a line a line

a line

Also, rg --multiline flag is not supported. Tho I was able to test it with let g:ctrlsf_extra_backend_args={ 'rg': '--multiline' }, it worked the same way as simulated above.

field	value
os	Ubuntu 20.04
vim	Vim 8.2
backend	ag 2.2.0
locale	en_US.UTF-8

• vimrc:

  let g:ctrlsf_ackprg = 'ag'

There is a fundamental problem that the line number in result pane is solid characters, which makes it difficult to match multiline objects (for highlighting) without interfering with line numbers.
