Empty Timers.TagsName and Timers.TagsValue when more than one timer tag provided

[FloatingMaster]

I mark timers with tags like these:
['group' => 'mongodb', 'operation' => 'find', 'collection' => 'collection_name']
But starting from some point Timers.TagsName and Timers.TagsValue become array of empty arrays in clickhouse:

┌─Timers.TagsName────┬─Timers.TagsValue──┬─Timers.Value──────────────────────────┐
│ [[],[],[],[]]      │ [[],[],[],[]]     │ [0.000167,0.00039,0.000063,0.000071]  │

I found that it happens when some values is long enough (like 30+ chars) AND there is more than one tag. It works fine with single tag and long values, but brokes when you add more (even if it has only 1 digit value)
