Description

For the license text https://www.gnu.org/licenses/old-licenses/gpl-2.0.txt I get the following:

System.out.println(Arrays.toString(LicenseCompareHelper.matchingStandardLicenseIds(licenseText)));
System.out.println(LicenseCompareHelper.matchingStandardLicenseIdsWithinText(licenseText));

outputs

[]
[GPL-2.0, GPL-2.0-or-later, GPL-2.0-only]

The two outputs should be the same since the GPL-2.0 license spans the whole file.
Tested with version 1.1.11
This problem is similar to 217

Research direction

Start by reproducing the discrepancy with the official GPL-2.0 text and the two entry points, matchingStandardLicenseIds and matchingStandardLicenseIdsWithinText. Trace how each method identifies standard licenses and verify that both produce the same IDs when the GPL-2.0 text spans the whole input.
