Can Kazakhstan nationals transit through Turkey now that entry to their citizens has been suspended?

My wife, from Kazakhstan, is looking for ways to get back to her home country after visiting me in the UK. She has recently been granted a visa extension until July 31 due to an inability to travel safely.

The COVID situation in KZ is worsening, and they are entering a second lockdown. Prior to this, for a very small window, the only way she could've entered KZ would've been flying from London via Istanbul. Now, Turkey has temporarily suspended entry to KZ citizens due to the new Kazakh lockdown.

In the event that the UK home office will not extend visas any further beyond July 31, my wife will be extremely hard-pressed to travel back to KZ on time. If she absolutely must leave, would it still be possible for her to transit through Turkey on her way to KZ? Or does suspended entry mean by all means, entry and transit alike?

I am highly concerned about her flying back to a country that is clearly still unsafe, but if the UK will not extend visas further, she will have no choice without overstaying.
