Latex matrices are not rendered when obfuscation/minification os enabled

[AndraxDev]

Since I could not reopen issue #464, I'm creating a new one because the bug is still here. Latex matrices are not rendered when obfuscation/minification is enabled. ProGuard rule -keep class org.scilab.forge.jlatexmath.** { *; } doesn't work for me. And the following rules also are not working (based on the source code):

-keep class org.commonmark.node.** { *; }
-keep class io.noties.markwon.ext.latex.** { *; }
