Issue description

Please describe the bug as clearly as possible.

When running tensorboard with a logdir that contains files generated via the tf.debugging.experimental.enable_dump_debug_info() function, during both training via the keras model.fit() function and inference via the keras model.evaluate() function, not all graph executions are reported in the div list in the upper right corner (see image).

Is there a way to force tensorboard to show all graph executions?
In case not, is there a way to force tensorboard to show a specific range of graph executions?

How can we reproduce the problem without additional resources (including external data files and proprietary Python modules)?

Possibly by running a large training and inference session which results in more than 883010 graph executions and debugging via the following function declaration:

tf.debugging.experimental.enable_dump_debug_info(
    dump_root=DUMP_ROOT,
    tensor_debug_mode='FULL_HEALTH',
    circular_buffer_size=-1
)
