Most likely when users might want to change 'tab-line-separator'
they will also want to apply text properties to it as well.
But the Customization UI doesn't support editing text properties.
This explains why, for example, 'eldoc-doc-buffer-separator' whose
default value contains text properties is not defcustom:
(defvar eldoc-doc-buffer-separator
(concat "\n" (propertize "\n" 'face '(:inherit separator-line :extend t)) "\n")
"String used to separate items in Eldoc documentation buffer.")

Well maybe because packages which have separator allows to customize
them (e.g which-key-separator, imenu-level-separator,
uniquify-separator), but I've noticed that most packages doesn't allow
changing the separator or are as plain variables
(e.g. menu-bar-separator, eldoc-doc-buffer-separator), i don't know if
this is a kind of coding convention, but if so then i'm closing this
bug.
