Tesseract takes much time when processing image

Current Behavior

Tesseract stucks (hangs) when processing specific file with with page segmentation mode: "SparseText".

Command:

"C:\Program Files\Tesseract-OCR\tesseract.exe" page.png page --psm 11 -l eng

Test File: https://drive.google.com/file/d/1zg0nHfiudF89PbER12U1Gi3lQzBcyoiw/view?usp=sharing

For reference reasons I am attaching original PDF (cause my goal is to do PDF OCR): 53402_01040415_doc002.pdf

Expected Behavior

Processing should perform fast like with segmentation mode: "Auto".
