Given I have a text like `'''Foo''' ('''bar''') ping pong`([[https://no.wikipedia.org/wiki/Bruker:Jeblad/test_of_syntax_highlight | this example]])
When I set the cursor inside a triple apostrophe and hit [space]
Then I expect a space to be inserted
Right now nothing happens, and I get the error
```
TypeError: readyTokens[readyTokens.length] is undefined
https://no.wikipedia.org/w/extensions/CodeMirror/resources/mode/mediawiki/mediawiki.js?96137
Line 928
```
This line is first statement after this test clause (`readyTokens[ readyTokens.length ].pos++; `)
```
if ( readyTokens.length > 0 ) { // it contains tickets before the point of rollback
readyTokens[ readyTokens.length ].pos++; // add one apostrophe, next token will be italic (two apostrophes)
mTokens = readyTokens; // for sending tokens till the point of rollback
} else { // there are no tikets before the point of rollback
```
This failure will then halt the execution and further editing will be blocked.
