Since SRT subs are directly sent to the client, a lot of the work is done by the client so it is partially/entirely up to how each client handles displaying SRT subs. From my own testing it seems that Firefox loses sync the most easily.
Some preliminary tests I did a while ago, but forgot to follow up on, was that remuxing the video with this command APPEARED to resolve the issue.
Even though the SRT subs were external in my case, it appeared that the +genpts+igndts options resolved any subtitle desync issue on the test video I had.

Code:
ffmpeg -fflags +genpts+igndts -i "/path/to/video.mkv" -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 newFile.mkv
