bug(syntax): F77 code highlighting cannot resolve a bare statement with line continuation

Is there an existing issue for this?

[X] I have searched the existing issues

Description

If the file https://github.com/scipy/scipy/blob/maintenance/1.14.x/scipy/optimize/lbfgsb_src/lbfgsb.f is opened in VS Code, the syntax highlighting comes quite nice all the way down to the line 967 and then gets confused on a naked format directive and cannot recover until the end of the file. On my system, it looks like the screenshot pasted below.

However, if I transfer a single character from 968 to 967 so format has at least something in the same line, it manages to recover. This leads me to believe that there is a greedy search for an argument after format line but cannot resolve the line continuation context.

      dsave(14) = stp
      dsave(15) = gdold
      dsave(16) = dtd

 1003 format (2(1x,i4),5x,'-',5x,'-',3x,'-',5x,'-',5x,'-',8x,'-',3x,
     +        1p,2(1x,d10.3))
 1004 format ('  ys=',1p,e10.3,'  -gs=',1p,e10.3,' BFGS update SKIPPED')
 1005 format (/,
     +' Singular triangular system detected;',/,
     +'   refresh the lbfgs memory and restart the iteration.')
 1006 format (/,
     +' Nonpositive definiteness in Cholesky factorization in formk;',/,
     +'   refresh the lbfgs memory and restart the iteration.')
 1007 format (/,
     +' Nonpositive definiteness in Cholesky factorization in formt;',/,
     +'   refresh the lbfgs memory and restart the iteration.')
 1008 format (/,
     +' Bad direction in the line search;',/,
     +'   refresh the lbfgs memory and restart the iteration.')
