black produces unnecessary line breaks in a cell of jupyter notebook if there are one or more import statements

## Diagnostic Data
- Python version (& distribution if applicable, e.g., Anaconda): 3.11.5 (Anaconda 2023.07)
- Type of virtual environment used (e.g., conda, venv, virtualenv, etc.): conda
- Operating system (and version): Windows 11 22000.2538
- Version of tool extension you are using: v2024.2.0 with black 24.4.2

## Behaviour
### Expected Behavior

Just like these code in one cell:
```python
from matplotlib.patches import Circle
data = {
"MACs": [0],
"MAPE": 1,
"Params": 2,
"Category": [
"Seq",
"Attn",
"Dyn",
"Dyn",
"Conv",
"Seq",
"Attn",
"Dyn",
"Dyn",
"Conv",
"Seq",
"Attn",
"Dyn",
"Conv",
],
}
```
When formatting, it should produce a line break after the import statement.
Other line breaks are unnecessary and annoying.

### Actual Behavior

It **Sometimes** produce formatted output like this:

```python
from matplotlib.patches import Circle

data = {
"MACs": [0],

"MAPE": 1,
"Params": 2,
"Category": [
"Seq",
"Attn",
"Dyn",
"Dyn",

"Conv",
"Seq",
"Attn",
"Dyn",

"Dyn",
"Conv",
"Seq",

"Attn",
"Dyn",
"Conv",
],
}
```
## Reproduction Steps:

It will **Sometimes** happen in large jupyter notebooks with many cells.
I find this issue in several notebooks containing private content. Here are an example file that could be shared:

[main.zip](https://github.com/user-attachments/files/15524459/main.zip)

If it's hard to reproduce, I'm willing to help.

## Logs:

I have set log level to trace but this issue disappears now.
Logs will be given when it happens again.

## Outcome When Attempting Debugging Steps:

Did running it from the command line work?

The command is something like `D:/anaconda3/Scripts/black.exe --stdin-filename e:\Project\battery\datapreprocessing_and_plots.py -`
It will get stuck since the file is `datapreprocessing_and_plots.ipynb` and there is no such file as `datapreprocessing_and_plots.py`.

## Extra Details

- What other Python-related extensions are you using?
- Are you working in a multiroot workspace?
I have been in a workspace, but with only one root `e:\Project\battery`.
- Any extra settings from your workspace or user settings.json files?
Here are the settings from the workspace:
```json
"settings": {
"python.analysis.inlayHints.functionReturnTypes": false,
"python.analysis.inlayHints.variableTypes": false,
"python.analysis.inlayHints.callArgumentNames": "off",
"python.analysis.extraPaths": [
"D:/ibl/brainnet"
],
"python.autoComplete.extraPaths": [
"D:/ibl/brainnet"
],
"python.analysis.logLevel": "Trace"
```
These are from settings.json of the profile:
```json
{
"jupyter.askForKernelRestart": false,
"flake8.args": [
"--ignore=E203,W503,F841,E501,F401,E741",

],
"[python]": {

```
There is no specific setting related to black or python in user settings.json.
