Incorrect Memory Leak Reporting

[orenbahari]

I am getting a ton of warnings in the engine, when I provide my logger to check if something is wrong with the engine itself.

[PDFiumEngine:MemoryManager][warn] Potential memory leak: 1 unfreed allocations. { args: ['Potential memory leak: 1 unfreed allocations'] category: "MemoryManager", source: "PDFiumEngine"} [PDFiumEngine:MemoryManager][warn] - 1781008: 1605652 bytes

The 1,605,652-byte allocation is the PDF file buffer loaded into WASM heap memory via memoryManager.malloc(length) in PdfiumNative.openDocumentBuffer() (direct-engine line 1068), seen here:

const filePtr = this.memoryManager.malloc(length); // 1,605,652 bytes = your PDF
this.pdfiumModule.pdfium.HEAPU8.set(array, filePtr);
const docPtr = this.pdfiumModule.FPDF_LoadMemDocument(filePtr, length, password);

This is not a memory issue and is freed if you destroy the document/engine. To solve this you have to ignore logging, which is bad.
