TypeError: Cannot read properties of undefined (reading 'offset') #374

Hello,

I get the following error when I try to load ce24e6fd-d4aa-4922-a91b-06c327a5c99b.tiff:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'offset')
    at blockedsource.js:271:29
    at Array.map (<anonymous>)
    at BlockedSource.readSliceData (blockedsource.js:259:19)
    at BlockedSource._callee$ (blockedsource.js:160:17)
    at tryCatch (blockedsource.js:2:1)

    at Generator.next (blockedsource.js:2:1)
    at asyncGeneratorStep (blockedsource.js:2:1)
    at _next (blockedsource.js:2:1)

The version that I am using is v2.0.7. Here is a code snippet to reproduce the issue:

let tiff = await GeoTIFF.fromUrl("./data/ce24e6fd-d4aa-4922-a91b-06c327a5c99b.tiff");

// throws """TypeError: Cannot read properties of undefined (reading 'offset')"""
let ifd = await tiff.requestIFD(0);

I am not 100% sure, but the current < top condition here might be the cause (should it be current <= top?). Could you please help me fix the issue?

The following issues might be related to this one:
