Preceding <TAB> breaks timestamps

[jgollenz]

Describe the bug

A <TAB> character that precedes a timestamp somehow breaks it. It does no longer show up in the agenda, one can't do <Leader>oo on it, ctrl-[x|a] is broken, org_timestamp_[up|down]_day is not working.

Steps to reproduce

See screenshot. foo is not working, all the others are (except for duh, here only the highlighting is broken).

Expected behavior

Would not expect any special behavior from preceding <TAB>
