Path length breaks spell check in Libre Fresh and Previous

I was editing a document with Libre Previous Writer and tried to turn on spell checking that underlines mis-spelled words in red.

I was unable to activate the feature and in the course of troubleshooting discovered that both Libre Fresh and Previous can not underline mis-spelled words in red if the install path is 58 characters long or greater.

OpenOffice underlined mis-spelled words fine with the default install path of 64 characters on my system.

I have the PortableAppsPlatform folder installed in C:\Portable which only adds 8 characters to the total length.

Windows 10, Libre Previous, LibreOfficeWriterPortable 7.4.5.1

Spellcheck does **not** work, mis-spelled words are not underlined in red:
C:\Portable\PortableAppsPlatform\PortableApps\LibreOfficePortablePrevious\
>> path length = 73 not including last backslash
C:\Portable\PortableAppsPlatform\PortableApps\Lib012345678\
>> path length = 58 not including last backslash

Spellcheck work fine, mis-spelled words are correctly underlined in red:
C:\Portable\PortableAppsPlatform\PortableApps\Lib01234567\ = 57 not including last backslash
>> path length = 57 not including last backslash
