Subject: vim-patch:8.2.4378: incsearch HL broken when calling searchcount in
 'tabLine' (#19147)

Problem:    Incsearch highlight broken when calling searchcount() in 'tabLine'
            function. (Mirko Palmer)
Solution:   Save and restore the incsearch state. (Christian Brabandt,
            closes vim/vim#9763, closes vim/vim#9633)
