Reported for: Toolset Views 2.8.3
When an HTML Conditional is used to display or hide content, and that conditionally-shown content exceeds (together with the HTML Conditional itself) a certain amount of characters, then shortcodes within that HTML Condition will not execute anymore.
This means your shortcodes that are shown conditionally may just be printed as shortcodes instead of rendering their content.
The number of characters needed in the conditional until the shortcodes are not executed anymore depends on the PHP version:
The language (PHP) in which most of WordPress and Views are written has a limit of the length it can take for a given feature. This is a limitation of the platform that Toolset cannot solve. In this case the pcre.jit limit is reached.
However, we do have plans to allow solutions (workarounds) to this limitation, which will eventually be part of future Toolset (Access) Releases, by passing entire Content Templates to Toolset Access shortcodes as an input source.
Until then you can simply use fewer characters within the same condition, to resolve the PHP limitation.
