First input ignored in notebooks when marking text

Hi Sperling,

 

Thank you for reporting this.

I am not aware of any known issue related to the first keystroke being ignored after selecting text in a Fabric Notebook. To help investigate further, could you please provide the following details?

• Browser name and version

• Whether the issue occurs in both existing and newly created notebooks

• Whether it happens in all cell types (SQL, PySpark, Markdown, etc.)

• Whether the behavior persists in an InPrivate/Incognito session

• A short screen recording showing the exact steps to reproduce the issue

As an initial check, please also try reproducing the issue in a different supported browser.

 

Once we have the above information, we can better determine whether this is a notebook editor issue or an environment-specific behavior.

 

Looking forward to your response

 

Thank you.

Hi Sperling, 

 

I've encountered this when quickly flipping between cells. Sometimes a cell will get stuck and not accept inputs. Clicking into another cell and thenback usually fixes it for me.  

Hi Sperling,

 

Thank you for the detailed information and for sharing the screen recording.

 

Based on your testing, the issue is reproducible across multiple browsers (Chrome, Opera, and Edge), occurs in both existing and newly created notebooks, affects all tested cell types, and persists in Incognito mode. This suggests the behavior is unlikely to be related to browser settings or extensions.

At this point, we are unable to identify a known issue or provide a confirmed workaround from the Community side. Since investigating Notebook editor behavior requires access to backend diagnostics and telemetry that are not available through the Community forum, I recommend opening a Microsoft Support ticket for further investigation.

Create a Fabric and Power BI Support Ticket - Power BI | Microsoft Learn

When submitting the ticket, please include:
The screen recording
Browser versions tested
Confirmation that the issue occurs in both new and existing notebooks
Confirmation that the issue reproduces across multiple browsers and in Incognito mode

This information should help the support and engineering teams investigate the issue more efficiently.

 

Thank you for bringing this to our attention.
