Steps to reproduce the issue

Try to add more than 30 tags in article.
Add simple 1,2,3,4,5,6,7,8,9,10,11,12,13,13,15,16,17,18,19.20,21,22,23,24,25,26,27,28,29,30,31
Is a limit 30 tags.
Tags setup:
Tag Entry Mode: AJAX

Now second bug is if you change to NESTED back to article and add
1,2,3,4,5,6,7,8,9,10,11,12,13,13,15,16,17,18,19.20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40, 41 missing, 42 missing, 43 add normal... (this happens once time it must be confirmed)
I save reload article etc. and still I can add 41 and 42

Expected result

NO limit add tags in AJAX metod

Actual result

LIMIT 30 tags in AJAX

System information (as much as possible)

J4.2.2
PHP 7.4 and VARS 10k

Additional comments

Btw. It is possible add more tags on once?
