To restore the tabs, you need to make a minor edit to one file:-

It's the "Linkurls.php" file which (on Ubuntu) is located at

/usr/share/php/Horde/Text/Filter/Linkurls.php

Edit line 89 from

(?:[a-z][\w-+]{0,19})?:/{1,3}  # URL protocol and colon followed by 1-3

to 

(?:[a-z][\w\-+]{0,19})?:/{1,3}  # URL protocol and colon followed by 1-3

i.e. insert a backslash to escape the "-"  after "\w"

That should clear up the tab problem. The errors you've pasted are unrelated
to that. On my system, I had to update a few Pecl extensions to install
PHP7.3 versions
