Double-click to select a word does not work

[KarolS]

plugin version 1.5

IntelliJ IDEA version 2021.3.1 Community Edition

Steps to reproduce:

1. Right click → New → Kick Assembler file
2. In the newly opened editor pane, type the following:
   The quick brown fox jumps over a lazy dog
3. Double click any of the previously written words.

Expected behaviour:

• The clicked word gets selected, like in every other IntelliJ IDEA editor, or elsewhere.

Actual behaviour:

• Only a single letter gets selected.

The flex and bnf files still need to be improved/reworked.

Any help on that front would be greatly appreciated.
