The Start Page doesn't display the Start button although the navigationButtonsVisibility property is set to "show"

[dinesh-58]

Describe the bug
I have hidden the navigation buttons in the survey's settings and then enabled auto advance. I also set the first page as a start page and it seemed auto advance doesn't work for the start page. So I made the navigation buttons visible for the first page to show the Start button. But doing so doesn't show the button. For some reason, if I set the nav buttons visible for the 2nd page, then the Start button shows properly on the start page.

Steps to reproduce

1. Create a survey
2. Create at least 2 pages
3. Go to Survey Settings > Navigation
   a) Ensure Survey Layout is set to "Original structure"
   b) Check "First Page is Start Page" and "Auto advance to next page"
   c) Set Show/Hide Navigation Buttons to "Hidden"
4. Select the First Page and open its settings.
   • Note: Clicking on a page seems to open the survey settings so you'll have to click on a page twice to open the page's settings
5. Go to Navigation and set Show/Hide Navigation Buttons to "Visible"
6. Run or embed the survey, but don't preview it. The start page won't show the start button.
   • Note: previewing the survey shows a different type of start button at the bottom that allows selecting a page. This button isn't shown when embedding the survey
7. Repeat steps 4-6 for the second page and now the start button will show

Expected behavior
I would like the Start button to be shown. Otherwise, there is no way to start the survey since auto-advance doesn't seem to work on the first page, and neither does the Enter key when the start page has text inputs

Please complete the following information:

• Browser: firefox
• Browser version: 133.0.3 (64-bit)
• JS framework/library: React, although this issue happens in the Creator Preview itself so I don't think this matters
• SurveyJS version: unsure. This is happening in the free demo for the SurveyJS Creator
• Device: PC

I checked the survey's JSON and that seems ok. Survey has "showNavigationButtons": "none" set and the first page has "navigationButtonsVisibility": "show"

Hello @dinesh-58,
Thank you for reporting this issue. I forwarded it to our developers for further investigation.

@andrewtelnov Andrew, please take a look at this usage scenario:

• A survey enables the auto-advance option.
• The first page is a starting page.
• Navigation buttons are disabled at the survey's level.
• Navigation buttons are enabled within the first (the starting) survey page.

Issue:

• The Start button doesn't appear in the first survey page.
• The auto-advance option doesn't work for the starting (the first) page.
  As a result, it is impossible to start a survey.
