Azure ML MLflow get_experiment_by_name() returns None for experiments with forward slash in name

[Harikrzna]

• Package Name: azureml-mlflow
• Package Version: 1.61.0.post1
• Operating System: Ubuntu 22.04.5 LTS
• Python Version: 3.12

Describe the bug
When using Azure ML's MLflow tracking URI (azureml://...), experiments with forward slashes in their names cannot be retrieved using get_experiment_by_name(), even though they can be created successfully and retrieved by ID.

To Reproduce
Steps to reproduce the behavior:

1. Create experiment with slash: client.create_experiment('dev_hka/test')
2. Try to retrieve: client.get_experiment_by_name('dev_hka/test') → Returns None
3. Can retrieve by ID: client.get_experiment(exp_id) → Works fine
4. Doesn't appear in search: client.search_experiments() → Not in results

Expected behavior
Either:
Option1: Experiments with slashes should be retrievable by name
Option2: Documentation of restriction on naming

Workaround:
Use underscore or hyphen instead of slash
