SAR session is closed only by timeout

Mesh SDK 5.0, SoftDevice S140 v7.2.0, NRF52840, SEGGER
------------------------------------------------------------------------------------
Hello,
My problem is that I can't send multiple SAR messages in sequence. After sending the first segmented message, I get a successful delivery callback (transaction_status_cb) and then I try to send the next segmented message, but this only succeeds as a result of resending and after a few seconds (because at the time the second message was sent, the previous SAR session is still open!). I left only one send to test, and I was able to find out that sar_ctx_free is being called on timeout a few seconds after my message was sent and I received confirmation. I did a search on Devzone and found at least 2 other mentions of the same issue that were never resolved. Does this mean Mesh 5.0 can't properly send segmented messages yet?
