I did this

Used CURL_WRITEFUNC_PAUSE (or curl_easy_pause) to pause a connection. CURLOPT_LOW_SPEED_LIMIT gets triggered once the download speed falls below the limit.

I expected the following

CURLOPT_LOW_SPEED_LIMIT not being triggered since I'm willingly in a paused state. Probably the paused connection should not be accounted in speed calculation while being paused.

Paused transfers should be be stopped due to slow speed. Additionally,
the slow speed timer is reset when the transfer is unpaused - as
otherwise it would easily just trigger immediately after unpausing.
