Robustify previous fix of onchange breakage

;; `before-change-functions' always records the whole word's `b-beg'
;; and `b-end'. Similarly, when coalescing two lines into one,
;; `fill-paragraph' they mark the end of the first line up to the end

;; a space. That's we keep markers _and_ positions so we're able to
;; detect and correct this. We ignore `beg', `len' and

;; from the markers. I've also experimented with doing this

Don't force eglot-strict-mode completely in eglot--dcase
Doing so was by design, since there's much ambiguity between the
CodeAction and Command objects. But 'disallow-non-standard-keys is
not necessary to disambiguate, and proved harmful in this bug.
To design a completion-in-region-function replacement that leverages
the elements in completion-at-point-functions, we must ensure that
their :exit-function parts execute in the correct buffer. That is the
buffer where the text to be completed lives, not necessarily the
buffer being used for user interaction.
Later on, this guarantee should be provided by Emacs itself, perhaps
by putting the correct with-current-buffer call in completion--done.
