HTML: line 79
Status: ✅ EXISTS

JavaScript: player.js:1865
HTML: line 89 (COMMENTED OUT)
Replacement: statistics-server (line 90)
Status: ❌ MISSING - WILL CAUSE CRASH IF ACCESSED
INITIALIZATION CONTEXT:
-----------------------
This code runs during error/crash reporting. The function attempts to collect
diagnostic information about the current state of the player, including
statistics data. The crash occurs while trying to build the diagnostic report
itself, creating a secondary crash during crash reporting.
The initialization happens in this context:
- User action or error triggers crash reporting
- System collects processor/memory information
- System collects statistics data for report
- Statistics module tries to read DOM elements
- Missing element causes null reference error
- Original crash report never completes
WHY THIS HAPPENED:
------------------
1. Translation effort started to convert Russian IDs to English
2. HTML file (player.html) had IDs changed from Russian to English
3. Original Russian IDs were commented out (not removed)
4. JavaScript file (player.js) was not updated to use new English IDs
5. Result: JavaScript references non-existent IDs
This is a classic case of incomplete refactoring where one layer (HTML) was
updated but the corresponding layer (JavaScript) was not updated in sync.

⚠️ EXECUTION HALTED ⚠️
Crash report could not be generated due to crash
while generating crash report
VERIFICATION STEPS TO REPRODUCE:
--------------------------------
1. Open player.html in browser with extension loaded
2. Trigger any error that would generate a crash report
3. Observe TypeError at player.js:743
4. Check browser console for "Cannot read property 'nodeType' of null"
5. Stack trace will point to common.js:220 (Узел function)
AFFECTED CODE PATHS:
--------------------
Primary (Immediate Crash):
→ player.js:1846 in ПолучитьДанныеДляОтчета()
→ Called during error reporting initialization
→ Blocks all crash reports from being generated
Secondary (Potential Crashes):
→ player.js:1865 when displaying server info
→ player.js:1995 when setting video codec info
→ player.js:2000 when clearing video codec info
All of these access missing DOM elements and will fail if executed.
