I've included a script below which should demonstrate the problem,
i.e. no completions are generated when the buffer-local value of
completion-ignore-case is t until the value of completion-ignore-case is
also set to t for the TAGS buffer.

I've tested on 29.2 and the master branch (as of a few hours ago).
## Generate a TAGS file.
printf "Function IsSingle\nFunction IsString\n" > functions
etags --lang=none --regex='/^function[ \t]+\([0-9A-Za-z:_]+\)/\1/i' functions
## Test default completion (case-sensitive).
emacs -Q --eval "(progn \
(pop-to-buffer (get-buffer-create \"test\")) \
(visit-tags-table \"TAGS\") \
(insert \"Is\") \
(complete-tag) \
(complete-tag))"
# 2 possible completions:
# IsSingle
# IsString
## Test case-insensitive completion (global).
emacs -Q --eval "(progn \
(pop-to-buffer (get-buffer-create \"test\")) \
(setq completion-ignore-case t) \
(visit-tags-table \"TAGS\") \
(insert \"is\") \
(complete-tag) \
(complete-tag))"
# 2 possible completions:
# IsSingle
# IsString
## Test case-insensitive completion (buffer-local).
emacs -Q --eval "(progn \
(pop-to-buffer (get-buffer-create \"test\")) \
(setq-local completion-ignore-case t) \
(visit-tags-table \"TAGS\") \
(insert \"is\") \
(complete-tag) \
(complete-tag))"
# No completions.
## Test case-insensitive completion (buffer-local, including TAGS buffer).
emacs -Q --eval "(progn \
(pop-to-buffer (get-buffer-create \"test\")) \
(setq-local completion-ignore-case t) \
(visit-tags-table \"TAGS\") \
(with-current-buffer \"TAGS\" \
(setq-local completion-ignore-case t)) \
(insert \"is\") \
(complete-tag) \
(complete-tag))"
# 2 possible completions:
# IsSingle
# IsString
