TeamCity messages for `BLOCK_OPENED` / `BLOCK_CLOSED` contain unresolved values `%s`

I was investigating KT-80074 and when I ran with --debug logs I saw a strange message in the output:

[KOTLIN] TCSM: ##TC[blockOpened name='JavaScript Unit Tests' flowId='%s']
...
[KOTLIN] TCSM: ##TC[testSuiteFinished name='TestSuite.Chrome Headless 138.0.0.0 (Mac OS 10.15.7)' duration='%s' flowId='karmaTC-137370689213989950']
...
[KOTLIN] TCSM: ##TC[blockClosed name='JavaScript Unit Tests' flowId='%s']

The values of duration and flowId are %s, not the actual values.
