TinyCME config generated after each member login

[sig-critchie]

Affected Version

cwp 2.2.3

Description

TInyMCE config is generated after each login, this seems to be due to "spellchecker_rpc_url" having a different "SecurityID" param, per user per session.

SilverStripe\Forms\HTMLEditor\TinyMCECombinedGenerator::generateFilename()

determines if the config needs to generated by hashing the output of

SilverStripe\Forms\HTMLEditor\TinyMCEConfig::getAttributes()

as the config is different each time, "assets/_tinymce" is being filled up with config files.

Expected Behavior

TInyMCE config is generated once.

Actual behavior

TinyMCE config is generated after each login.

Steps to Reproduce

1. Logout of the CMS
2. Login to the CMS
3. Browse to a page with an HTMLEditorField

Thanks for the report. The impact of this is that users need to download the TinyMCE configuration files more often than they should?
