PDF is [Sample lease contract 26.pdf](https://github.com/mozilla/pdf.js/files/1500985/Sample.lease.contract.26.pdf)

Steps to reproduce the problem:
I am using [https://mozilla.github.io/pdf.js/web/viewer.html](url) to preview pdf by opening the pdf.

now am searching for "**made is**" but its not showing in the pdfjs

and while selecting and copying pdf  text it has no space in b/w words

expect(reason instanceof InvalidPDFException).toEqual(true);
        expect(reason.message).toEqual("Invalid PDF structure.");
      }
      await loadingTask.destroy();
    });
    it("creates pdf doc from non-existent URL", async function () {
      if (!isNodeJS) {
        
        pending("Fails intermittently on Linux in browsers.");
      }
      const loadingTask = getDocument(
        buildGetDocumentParams("non-existent.pdf")
      );
      expect(loadingTask instanceof PDFDocumentLoadingTask).toEqual(true);
      try {
        await loadingTask.promise;
        
        expect(false).toEqual(true);
      
        expect(reason instanceof MissingPDFException).toEqual(true);
      }
      await loadingTask.destroy();
    });
    it("creates pdf doc from PDF file protected with user and owner password", async function () {
      const loadingTask = getDocument(buildGetDocumentParams("pr6531_1.pdf"));
      expect(loadingTask instanceof PDFDocumentLoadingTask).toEqual(true);
      const passwordNeededCapability = createPromiseCapability();
      const passwordIncorrectCapability = createPromiseCapability();
