What happened?

After stopping a program from running, by hitting the feed hold button and then clicking the reset button next to the resume button and progress bar in the GRBL panel of the WebUI, the tool length offset TLO is reset to zero.
When the program is restarted, this causes the tool to be smashed into the stock.

TLO should not be reset by any event that does not also reset the machine position, ie firmware restart or power loss (or the reset TLO comand).
