Environment

dash 2.9.2 

Describe the bug

In Dash 2.9.2, the clientside callbacks defined inline get a random function name which seems to break. Note: the issue solves itslef when refreshing the page, however every first load triggers this issue. Tested in 2.9.1 and this does not happen, it was introduced with the random function names in 2.9.2.

Using a deterministic function name instead solves the issue:

import itertools COUNTER = itertools.count() def register_clientside_callback(...): ... increment = next(COUNTER) function_name = f"inline-script-{increment:06d}" ...

Expected behavior

The clientside_callbacks defined inline should work from the first load.
