After creating a pagelayout override for kernel errors, it only works the first time the error is displayed (for that url).
Subsequent page hits/refreshes display the page with the "standard" layout.

Steps to reproduce:

1. Create a new legacy template design/standard/templates/pagelayout_error.tpl
2. Add the following to override.ini.append.php

   [pagelayout_error_1]
   Source=pagelayout.tpl
   MatchFile=pagelayout_error.tpl
   Subdir=templates
   Match[error_type]=kernel
   Match[error_number]=1
   
   [pagelayout_error_2]
   Source=pagelayout.tpl
   MatchFile=pagelayout_error.tpl
   Subdir=templates
   Match[error_type]=kernel
   Match[error_number]=2
   
   [pagelayout_error_3]
   Source=pagelayout.tpl
   MatchFile=pagelayout_error.tpl
   Subdir=templates
   Match[error_type]=kernel
   Match[error_number]=3
   

3. Access an uri that will generate a kernel error ( /content/view/full/123456789 )
4. Refresh the page

Notes:

This seems to occur only with some kernel errors (1,3) and not others (20,21)
