Navigator Object behaves weirdly when encountering dashes

[anneangersbach]

Steps to reproduce:

1. Enable the Navigator Object in the NVDA vision options
2. Open the following website in Chrome, Edge or Firefox: https://www.teamviewer.com/en/pricing/overview/?force-country=RO&tab=Teams
3. Find the area for "Compare license features"
4. Navigate the comparison table with the up and down arrows.
   1. icons will be ignored
   2. text will be read out
   3. a dash will cause the Navigator Object to highlight the entire frame and sometimes jump up or down in the scroll position

Actual behavior:

Navigate the comparison table with the up and down arrow keys.
For easiest visible results use the section about "Software Integrations".
On reading dashes the Navigator Object will highlight the entire frame and sometimes jump up or down in the scroll position.
In Firefox the issue exists, too. Although the Navigator Object is a bit less weird with the highlight - it highlights the entire table on dash and does not seem to jump around.
Edge behaves the same as Chrome.

Expected behavior:

The Navigator object should behave as it does with all the other text content - highlighting the dash and staying at the expected scroll position.

Other questions

Does the issue still occur after restarting your computer?

Have you tried any other versions of NVDA? If so, please report their behaviors.

yes, same issue with the beta provided through the comments, although slighty different visual style of the too large navigator object box.

If NVDA add-ons are disabled, is your problem still occurring?

yes

Does the issue still occur after you run the COM Registration Fixing Tool in NVDA's tools menu?

yes

Can you try the latest NVDA 2025.1 beta8?

I have not reproduced the problem in the latest NVDA alpha version and in Firefox and Chrome.

[anneangersbach]

I tried, unfortunately it still happens, only the bad jumping is gone.
I also tried in an incognito window in Chrome, it also happens there.
Maybe there's something in my nvda.ini that will help. I can also create more screen recordings if that's helpful.

I can aslo try on my personal mashine later tonight, see if it reproduces there or not.

Welcome @anneangersbach ,
We are unable to process this issue as it stands.

• You have indicated that this issue is not present with add-ons disabled. Is this accurate?
• Please reproduce this issue and provide a log file of the behaviour with add-ons disabled. Ensure your log level is set to debug in general preferences.

Kind Regards,
NV Access Software Developers

Hi Sascha,

I must've misread that then, I have zero add-ons installed, just NVDA out of the box and a few settings to make it easier for me as a developer using it for testing (i.e. voice volume down to zero and instead using speech viewer most of the time). The settings should be attached in my previous post.

I have edited the original post to rectify this and also the answer regarding other versions, as I have tried it with the beta that was provided through hwf1324.

Here's my log output for using the site. I used Vivaldi (Chromium) and Firefox while the log was running. Both browsers show the issue in slightly different visual styles.

I have encountered this on other pages I was testing now as well, although I have not looked too deeply into the elements that caused it in those instances. When I continue testing the pages tomorrow I can pay more attention and record the other elements its caused on, too.
